Seems to be ok now.

It just switched from an error page to their usual maintenance page for me.

1 second edit: And back to "The service is unavailable" error page.

And a moment later: Got it to load, then refreshed and back to error. Just seems really flaky.

Every other page load fails for me. I get 3 different pages

1. The page I'm looking for

2. A Content-Type: text/html, body: "The service is unavailable." page

3. A more elaborate "Stack Overflow is currently offline for maintenance" page

I recall reading an article, years ago, how stack overflow is ran off of the equivalent of like two on-prem servers that could take the load way better and far more cheaply than an "enterprise cloud architecture" could.

I thought it was an amazing example of how expensive it is to be in the cloud. I didn't think about the high availability benefits of the cloud...

Think they still run off of a few servers or did they ever migrate to the cloud?

The cloud has outages too, though. If you've been here long enough you've seen plenty of cloud-related outages. The truth is, outages happen, on cloud or otherwise. They might've avoided this but they might've been hit by yesterday's AWS outage. [0]

I don't think they'd gain much from migrating, and to the best of my knowledge they haven't.

I don't recall seeing anything in the last couple few years that indicated anything changed
