> why not wifi?

I'm not the author but can speculate. WiFi is higher latency and a bit probabilistic. Like the slowest 1% of requests to the server may take an additional 1000ms or so. And if I was running a blog from a phone I'd want it to be impressively fast. Also an old Android phone may not be able to use modern WiFi standards and it could struggle with the traffic from being on the HN homepage.

Old phone? It's a Pixel 5 from five years ago. My first Android ever in 2012 already supported 802.11ac with speeds faster than any internet connection I've ever had

Are you sure? Supporting 802.11ac in 2012 is pretty amazing considering that the standard was finalized in late 2013.

		Oh, you're right. I was quite sure but it's indeed 802.11n. Maybe I thought it was an upgrade from the other systems (laptop and phone) I had at the time because it was the first with 5 GHz, seeing new WiFi networks that no other of my devices could see, and conflated that with the new standard. That's still faster than the internet connection I have and host my website on today, but not by as much
