Looking forward to the post mortem on this one. We weren't affected (just using the CDN), and people are saying they weren't affected who are using Cloudflare Workers (a previous culprit which we've since moved off), so I wonder what service / API was actually affected that brought down multiple websites with a 500 but not all of them.

Wise was just down which is a pretty big one.

Also odd how some websites were down this time that previously weren't down with the global outage in November

This is not good. One major outage? Something exceptional. Several outages in a short time? As someone thats worked in operations, I have empathy; there are so many “temp havks” that are put in place for incidents. but the rest of the world won’t… they’re gonna suffer a massive reputation loss if this goes on as long as the last one.

Yes.

Weird that https://www.cloudflarestatus.com/ isn't reporting this properly. It should be full of red blinking lights.

Wow, just plain 500s on customer sites. That's a level of down you don't see that often.

https://downdetector.com/ classic

This is second time this week: https://news.ycombinator.com/item?id=46140145

The previous one affected European users for >1h and made many Cloudflare websites nearly unusable for them.

I'm just realizing how much we depend on Cloudflare working. Every service I use is unreachable. Even worse than last time. It's almost impossible to do any work atm.

Love that Cloudflare put together a participative and community-driven advent calendar!

That's the 30% vibe code they promised us.

Cynicism aside, something seems to be going wrong in our industry.

https://downdetectorsdowndetector.com/ is up :) but the status is not correct.

If I had a nickel for everytime cloudflare went down. Then I would have 2 nickels which is not a lot but still wierd that it happened twice.

The site is back up, but it feels fairly silly that a platform that has inserted itself as a single point of failure has an architecture that's got single points of failure.

The other companies working at that scale have all sensibly split off into geographical regions & product verticals with redundancy & it's rare that "absolutely all of AWS everywhere is offline". This is two total global outages in as many weeks from Cloudflare, and a third "mostly global outage" the week before.

How interesting. As of 00:30 or so I could still access Claude but then it went down with a 500 from Cloudflare and I thought I'd nab a quick something off Slickdeals but that's down too. My own blog is on Cloudflare's `cloudflared` tunnel and it's working just fine, even the cache, so it must be something hitting some specific type of configuration or some shard hitting some region.

And they're back before I finished the comment. Such a pity, I was hoping to hog some more Claude for myself through Claude Code.

Claude offline too. 500 errors on the web and the mobile app has been knocked out.

For those saying we have an over-reliance on software -- is there a way to use multiple CDNs for the same frontend website?

I can imagine the horror of pressure of the people responsible for resolution. On that scale of impact it is very hard to keep calm - but still the hive of minds have to cooperate and solve the puzzle while the world is basically halted and ready to blame the company you work for.

Cloudflare uptime has worsened a lot lately, AI coding has increased exponentially, hmm

I moved away from Cloudflare over a month ago because I didn't understand how they don't have pricing caps for their upgraded plans, they genuinely seem like the mob but I haven't looked any further into it..

Either way it's been interesting to see the bullets I've been dodging.

I have 10B idea: cloudflare that does not fail so often.

So many outages now they all begin to swim into 1, what's that 3 or 4 this quarter?

I don't want to criticize cloud flare, I love what they do and understand the scale of the challenge, but most people don't and 2 in a month or so like this is going to hit their reputation.

Somebody at Cloudflare is stretching that initial investigation time as much as possible to avoid having to update their status to being down and losing that Christmas bonus.

I just started getting npm errors while developing something; I was like hmm, strange... then I tried to go down to isitdown. That was also down. I was like, oh this must be something local to me (I'm in a remote place visiting my gramps).

Then I go to Hacker News to check. Lo and behold, it's Cloudflare. This is sort of worrying...

This is painful, if I'm not mistaken this is during a scheduled maintenance too ?

Whenever I deploy a new release to my 5 customers, I am pedantic about having a fast rollback.. Maybe I'm not following the apparent industry standard and instead should just wing it.

Even LinkedIn is now down. Opening linkedin.com gives me a 500 server error and Cloudflare at the bottom. Quite embarassing.

Perhaps related? My main fiber WAN went out few hrs ago, failing over to Starlink backup. Discovered it’s a cloudflare issue, as my multi-wan setup tests against 1.1.1.1, which suddenly stopped responding (but only from my fiber ISP). Switched to testing 8.8.8.8 to restore.

If it weren’t for recent cloudflare outages, never would have considered this was the problem.

Even until I saw this, I assumed it was an ISP issue, since Starlink still worked using 1.1.1.1. Now I’m thinking it’s a cloudflare routing problem?

Their uptime over the year is likely faring worse than your average hosting company, DNS provider or CDN.

Free accounts seem to be fine, only enterprise accounts seem to be affected.

Our site is fine, including files served by Cloudflare's CDN and Cloudflare Workers, but the Cloudflare dashboard is definitely down.

The Cloudflare status page says that it's the dashboard and Cloudflare APIs that are down. I wonder if the problem is focused on larger sites because they are more dependent on / integrated with Cloudflare APIs. Or perhaps it's only an Enterprise tier feature that's broken.

If it's not everything that is down, I guess things are slightly more resilient than last time?

Wow, three times in a month is really crushing their trust.

https://www.tandfonline.com/doi/full/10.1080/02673843.2023.2... https://www.perplexity.ai/ https://www.researchgate.net/

All give me

"500 Internal Server Error cloudflare.."

So I'm guessing yes.

For us also Digital Ocean, Render, and a few other vendors are down.

At this point picking vendors that don't use Cloudflare in any way becomes the right thing to do.

What ever happened to "no deploys on fridays"? haha

Isn't it happening a little too often now? Did someone .unwrap in production again?

Is it at all achievable to be fronted by a CDN but fallback to the raw server in case the front falls off? Better to be vulnerable to DDoS than be unreachable altogether

So, I understand correctly that all websites and services want protection from DDoS attacks, and that's basically their number one concern. The second is caching in different parts of the world. So, it's caching and DDoS. But at the same time, nobody wants to use CloudFront from AWS because it’s not that simple yet. And it’s more expensive, while Cloudflare is free. So, what should we do about all this? This won’t do. We’ve created a gigantic bottleneck that controls the entire internet, just like in the movie Mad Max, where he controlled the only source of water. That’s wrong. And we all fell for it like fools. So, the question is, what can be done in this situation? Are there reliable competitors? Are there any fault-tolerant systems for this? The whole problem is that our DNS, and with Cloudflare, they proxy it. So, if their proxy goes down, everything falls apart. What should we do about this?

Just after Matthew Prince's interview at Wired :)

https://news.ycombinator.com/item?id=46157295

Wonder if supabase auth down is also related https://status.supabase.com/incidents/rgz3dl2rcmq8

Interestingly enough, also some MS/Azure services are down. For example https://www.office.com/ just returns:

>We are sorry, something went wrong. >Please try refreshing the page in a few minutes. If the problem persists, please visit status.cloud.microsoft for updates regarding known issues.

The status page of course says nothing

I use Cloudflare because of their Tunnel to protect my Raspberry Pi, but I think I will just use it without the Tunnel now. My main concern is privacy, but I'm not ready to accept so frequent downtime and dependence on them. The whole reason to host self-host was to be independent anyway. Does anyone have a recommendation for that (that is free)? Should I worry about privacy? My name and my city are on the website anyway.

Classic. https://imgur.com/a/B3QxB1R

At least the 500 error announces ownership.

Imagine how productive we'll be now!

This is getting embarrassing.

looks like a big one. interestingly, our site, which uses a TON of Cloudflare services[0] — yet not their front-line proxy — is doing fine: https://magicgarden.gg.

So it seems like it's just the big ol' "throw this big orange reverse proxy in front of your site for better uptime!" is what's broken...

[0] Workers, Durable Objects, KV, R2, etc

"Scheduled maintenance is currently in progress" I image the maintenance was conducted like this: "fix detroit data center bugs, please be very careful, don't mess up like last time :)" bypass permissions on

They had a scheduled maintenance between 7am and 11am UTC in Chicago. But that should have re-routed traffic not take down internet right?

Luckly https://downdetectorsdowndetectorsdowndetectorsdowndetector.... is up :)

LOL, 500 returned for many big sites…this is going to hurt and make people rethink. If it’s not DNS, then someone pushed to production on Friday :-)

Notion is also down (haven't seen a comment on that). It's so funny how the biggest companies literally just have their sites not loading because of Cloudflare.

Some of the sites I maintain, are fine. But I'm guessing it's just a matter of time?

https://www.researchgate.net/ https://www.tandfonline.com/ https://www.perplexity.ai/ All give me "500 Internal Server Error cloudflare"

So My guess is yes It´s down.

Just started working for me again (in Germany), both on our own CF-hosted page and on cloudflare.com itself.

It's really cool to me that this site is never down with all these outages of major websites.

Representative of having the best developers behind it.

> Monitoring - A fix has been implemented and we are monitoring the results.

Everything i use depend on perfect cloudflare operation workflow, practically 99% of these services go down. What magical qualities it has that no competitors form for its services?

https://registry.npmjs.org/ is down, affecting our builds

I can still visit some websites that use Cloudflare, but other don't work.

Blender Artists works, but DownDetector and Quillbot dont.

It's configuration error or related to configuration. It always is with this big things.

Nice thing about Cloudflare being down is that almost everything is down at once. Time for peace and quiet.

for me docker is failing with:

    unknown: failed to copy: httpReadSeeker: failed open: unexpected status from GET request to https://production.cloudflare.docker.com/registry-v2/docker/registry/v2/blobs/sha256/....

downdetector is also down

Yeah, and because of this for example Claude Code is down too because the auth goes through CF. F*cking marvelus, the decentralized web ...

I can't update DNS entries for my domains with Porkbun, because it's "Powered by Cloudflare".

CloudFlare: You can't go down if you're never up.

Heads will roll at cloudfare. E-commerce customers must be furious.

Impossible not to feel bad for whoever is tasked to cleanup the mess.

Basecamp was down couple of minutes ago and it's back now online.

Some big fishes were affected as well... Crunchyroll, Fortnite, LinkedIn let's wait for the explanation of this one.

I'm looking for cofounders and investors to build a working cloudflare.

"In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary. Dec 05, 2025 - 07:00 UTC"

No need. Yikes.

It's ok to fail. but the most frustrating thing ever is... there's no contact point or supporting team easily and directly accessible.. this is bad..

It seems regular reverse proxying and R2 still works, as we use those and seem to be working fine still.

Can't get to the Dashboard though.

DownDetector'sDownDetector does not detect that DownDetector's down

Interested if its the same issue that brought down Cloudflare previously.

Pretty awkward. Thought my WIFI was acting up when I wasn't even able to pull up the Cloudfare website to see if something was down. Then, trying to go to Downdetector and that wasn't working either.

LinkedIn and MEdium are also down as a result

Everyone says vibe coding but people are just fine at being incompetent without the AI help

It is up for me.

All the sites that were 500 error before are able to load now.

No engineers from Cloudflare reading hackernews these days? Should update your status page!

It's ok to fail, but most frustrationg thing is there's no suppoting team or any contact point accessible directly. this is bad..

https://sniffies.com is back and running.

Cloudflare is back.

Congratulations all.

Cloudflare is investigating issues with Cloudflare Dashboard and related APIs.

Looks like (some) sites behind Cloudflare still work if they do not have caching on.

How do you tell if this is a cyberattack or not?

One has to wonder how many times or how often proprietary cloud services have to go down before there is a general shift away from using the cloud and "infinite scaling" for everything. For many, many use cases you do not need neither Cloudflare nor Github nor nine nines for everything (which you are clearly not getting anyway). It's obviously not enough with once a year for most businesses, or perhaps once a month. Weekly outages? For how long?

If you host something that actually matters that other people depend upon and, please review your actual needs and if possible stop making yourself _completely_ dependent on giant cloud corporations.

Maybe they should stop vibe coding and vibe reviewing their PRs?

NPM is down. World is collapsing thanks to Cloudflare.

They had a few good weeks.

what's the estimated loss? any guesses or estimations?

seems related to CF tunnels... policies are being enforced but perhaps origin servers are not being properly served.

Never push to production on Friday!

i was watching the climax of "Fullmetal Alchemist: Brotherhood" on crunchyroll and cloudflare went down again

Godspeed, Cloudflare, for the fix

I wonder how many uptime SLAs will be violated this year.

They're back online it seems

Really disappointed that down detectors down detector[1] isn't detecting that down detector[2] is down

[1] https://downdetectorsdowndetector.com/

[2] https://downdetector.com/

Shortest damn outage ever

how long cloudflarestatus.com takes it to detect usually?

NPM is down as a result.

It is up again. There will be a lot of hard talk with Cloudflare, I guess

Just in time for the London work day :)

500 internal server error on most things:

500 Internal Server Error cloudflare

This is so cool guys. All of us get to lose millions of dollars together so late at night!

eval(requestBody).unwrap()

All those enterprise architects must be fuming now

Ooof status 500 someone’s getting fiiiiired!

This is not a good look, at all

Anyone shorting the damn stock?

Hah even Linkedin is showing 500 for me

My company's services went down as well.

Even digital ocean is down :D

Curious to see which big companies were caught flat-footed during the 18 November outage compared with today. In my opinion, if a company was caught out twice, that reflects poor decision-making and urgency. As the saying goes, fool me once, shame on you, fool me twice, shame on me.

If a company was able to overcome all the red tape within three weeks and not be impacted today, that's impressive.

Looks to be back now.

Shopify is down.

This gotta be an attack, no way its configuration error again.

Infrastructure-as-Vibe?

Seems to be back up?

Seems to be back up.

That's quite unfortunate xD

for all of 20 minutes, the world cried.

It's back!

How is Hacker News still up?

it's back on

but wow, it must be stressful to deal with this

What a joke of a company. They have the internet in the palm of their hands, and yet let vibe coding ambitions ruin their empire.

Time for everyone to drop this company and move on to better solutions (until those better solutions rot from the inside out, just like their predecessor did)

"Given Cloudflare's importance in the Internet ecosystem any outage of any of our systems is unacceptable. "

Is this a joke?

And their blog of above statement is also down:

https://blog.cloudflare.com/18-november-2025-outage/

HaHa -Nelson

It's back.

aw, i cant go on rateyourmusic

Someone's been vibe coding the scheduled maintenance.

This got me and the anime community stressed

Notion is also down as a result

I can absolutely accomplish nothing today...can't download npm packages, cannot login to services.

I've been a Cloudflare fan for the longest time, but the more they grow the more they look like the weak link of the internet. This is the second major outage in less than few weeks. Terrible.

And it's on Friday again — never change, Cloudflare.

Gentle reminder that every affected company brought it upon themselves. Very few companies care about making their system resilient to 3rd party failures. This is just another wake-up call for them.

Turnstile seems up still.

>Go to <social media page> - 500 error from cloudflare >Google is <social media page> down -> click first link - literally the exact same 500 cloudflare error html from downdetector

Ooof, this one looks like a big one!

and many more I won't add bc I don't want to be spammy.

Edit: Just checked all my websites hosted there (~12), they're all ok. Other people with small websites are doing well.

Only huge sites seem to be down. Perhaps they deal with them separately, the premium-tier of Cloudflare clients, ... and those went down, dang.

LinkedIn, Perplexity as well

Round 2 of Cloudflare outages.

We can now see which companies have failed in their performative systems design interviews.

Looking forward to the post-mortem.

I was just arguing yesterday to coworkers I would quit tech before helping centralize any more of the internet on Cloudflare as a massive single point of failure.

Thank you, Cloudflare, for again proving my point.

Perplexity AI shows 500 Internal Server Error

My Shopify store is down. My competitor stores are also down.

LinkedIn is down

Update title to “Tell HN: Cloudflare was down”

Just experienced this and came here to check, because even their website is down. The referenced link also returns with 500.

Cloudflare just closed down the incident on their status page without any additional explanation. Sigh.

seems its back \m/

claude.ai is down bc of it :( good for OpenAI as they're using something else maybe Vercel?

Clownflare strikes again!

Just a reminder that every dependency you rely on, both inside your codebase and external services, has a price.

>half internet down >first "is site down" result (downdetector) down >downdetectorsdowndetector.com: "everything is fine" >downdetectorsdowndetectorsdowndetector.com: not even responding >downdetectorsdowndetectorsdowndetectorsdowndetector.com: "everything is broken"

I noticed this when my Claude iPhone app stopped working.

I love it, and we wont learn from this again :-) Looking forward for the 3rd outage in a few weeks.

Nice, just got woken up by my outage alarms, just for it to be Cloudflare again. At least it's _my_ problem!

But my goodness, they're really struggling over the last couple weeks... Can't wait to read the next blog post.

gitlab.com hasn't noticed yet.

This is so cool guys!!! We all get to savor this moment and lose millions of DOLL HAIRS together!!

Obligatory song https://www.youtube.com/watch?v=OC06Z6lCB_Q&t=30s

cloudflare pages seems to be working!

Wishbone12

Odd

As is supabase

I’m sure everybody learnt their lesson from last months outage and built in redundancy or stopped relying on Cloudflare.

Every time Cloudflare is down I'm not sure if it's really down or not because most down detector websites use Cloudflare. Lmao

and it's back

Went to ahref to check a domain, saw 500 and came here to check.

I have a few domains on cloudflare and all of them are working with no issues so it might not be a global issue

I wonder if it is another bug , like unwrap, in their rewritten code.

Also, I don't think their every service got affected. I am using their proxy and pages service and both are still up.

she's back

stock going whoops

Is anyone else woken up by this? My company's service is down too. Considering a move away

Perplexity is down

https://www.cloudflarestatus.com/incidents/hlr9djcf3nyp

>We will be performing scheduled maintenance in ORD (Chicago) datacenter

>Traffic might be re-routed from this location, hence there is a possibility of a slight increase in latency during this maintenance window for end-users in the affected region.

Looks like it's not just Chicago that CF brought down...

"Monitoring - A fix has been implemented and we are monitoring the results."

Internet-level companies are having more outages recently. Is the exposed surface area increasing or is the quality of service suffering?

Interestingly, my site running on workers https://codeinput.com is still functioning. Worth mentioning that I don't use Cloudflare firewall/caching (directly exposed workers)

Claude RIP

seems to have been resolved

Up again!

claude code works tho

waaay too soon

"I warned you about Cloudflare bro!!!! I told you dog!"

shopify.com

yes...

It's up now!!! London, UK

my shopify store is down

Aaand ... we're back!

gitlab down aswell

Aaand ... we're back

wtf, cannot work now

Tried to watch anime then realized that cloudflare was down...again. smh

Tried to watch anime and then i realized it was down....again. smh

pixiv.net

it's fine now...I believe

It is up now!

Are you serious?

Who knows, maybe it will be because of C or C++ this time. Or something else.

Funny how even safe Rust isn’t able to stop vibecoding without a proper validation. And the fact that it's a monopoly isn't so funny anymore.
