Perspective from the trenches: I teach at a university that uses Canvas. We are in our final exams period right now.

We got our first email (from Academic Affairs) notifying us that it was down at 5:17pm EDT this afternoon, with little info; followup emails were sent at 6:24 and 6:57 with more info, but mostly about how we would be compensating for it and not about what actually was going on (other than, "nationwide shutdown" and "cybersecurity attacks", no further detail). I don't get a sense that they know much more than that, not that I would expect them to.

A perhaps telling detail: they're instructing us to have students email us directly with any work that had been submitted via Canvas. That suggests that they have no particular confidence that it will come back up soon.

I personally am only slightly affected; as a CS professor a lot of my students' work is done on department machines, and submitted that way, and I do the actual exams on paper. More importantly, I've never liked or trusted Canvas's gradebook, and so although I do upload grades to Canvas so students can see them, my primary gradebook is always a spreadsheet I maintain locally.

But I have a lot of colleagues for whom this is catastrophic at a level of "the whole building burnt down with all my exams and gradebooks in it"---even many of those that teach 100% in person have shifted much or all of their assessment into Canvas (using the Canvas "quiz" feature for everything up to and including final exams), and use the Canvas gradebook as their source-of-truth record. We've been encouraged to do so by our administration ("it makes submitting grades easier"). For faculty in that situation, they have few or zero artifacts that the students have produced, the students themselves don't have the artifacts to resubmit via email because they were done in Canvas in the first place, and they have no record of student grades or even attendance (because they managed that all inside Canvas). I guess they have access to the advisory midterm grades from March, if they submitted them (most do, some don't), but that might be it.

My gut feeling on this is that this is either resolved in hours (they have airgapped backups and can be working as soon as they can spin up new servers), or weeks (they don't). Very little in-between. And if that's true and we wake up tomorrow with this unresolved, I really have no idea what a lot of professors at my university and across the country are going to do to submit grades that are fair and reasonable. In the extreme case, they may have to revert to something we did in the pandemic semester (and before that, at my school, in the semester that two major academic buildings actually did burn to the ground a week before finals): let classes that normally count for a grade just submit grades as pass-fail. Because what else can you do?

(Well, one thing you can do is not put your eggs all in one basket, and not trust "the cloud" quite so much, but that ship's already sailed. I do wonder if in the longer term, anybody learns any lessons from this....)

UPDATE: As of 11:45pm EDT, my university's canvas instance is up and running! Here's hoping it stays (but I'll be downloading some stuff just in case...)

> the students themselves don't have the artifacts to resubmit via email because they were done in Canvas

It’s so simple to send an e-mail to the student with relevant records on completion of a quiz or whatnot. They don’t do it, because they want to control the data. (And universities don’t insist on it for who knows what reason.)

Just to add one more data point, we also use Canvas at my university. The deadline for submitting who are eligible (i.e. passed compulsory assignments and labs) to take the exam was yesterday, and I couldn’t meet that deadline because Canvas went down. I usually do corrections offline so I have backups of my own evaluations, but these are courses with many teachers and many TAs, so Canvas is the way we sync our assessments.

I work in the Education sector as IT. We don't know much else either.

Everything we know has come from reddit threads / hackernews threads. There has been 0 official communication today indicating this was an attack, yet the login page was defaced by ShinyHunters.

I don't understand what's the panic and doomerism about. Any competent IT team has backups and will be up and running as they go back to a state before the breach. This is HN. I'm disappointed that everyone is talking about losing grades and going back to pen and paper. I don't see how that could happen in 2026.

And from the hacker's message itself, it's clear they want money in exchange for not releasing private info, not for the data itself.

Do we live in a fear based culture? Why the panic? Even if everything was hosted on Instructure's infrastructure, it's all AWS. I'd be VERY surprised if there aren't multiple way to go back to a previous state.

Most of the work and delay is to make sure they figure out where the breach occurred.

Maybe a hybrid approach. Scramble to create a final exam/project and give them the option to do pass/fail or a real grade, their choice.

And then wish for the death of saas and a day where you can deploy your own software you can control and modify as you need.

> they have airgapped backups and can be working as soon as they can spin up new servers

... and assuming they have a documented, tested, and trusted restore process.

To my European ears this just sounds like a disaster like this waiting to happen. God bless the annoying privacy OSS advocates and bureaucrats, I guess.

Backups are definitely helpful in ransomwares, but before systems can be restored and brought back online, victim organizations still need to assess the scope of the breach, find the initial access vector, identify compromised accounts, and evict the threat actor. That can take time.

> let classes that normally count for a grade just submit grades as pass-fail. Because what else can you do?

Schedule a single exam and that's your grade for that subject? That's how it should work anyway, credits for work during semester (or worse attendance) are not needed to evaluate if someone learned the material, give them an exam and done.
