As promised, I migrated Stackage.org to a new server yesterday. Unfortunately, some time afterward, the server process froze and remained unresponsive. I didn’t learn about the problem until the next morning (obviously a problem by itself), at which point I was able to restart the process.
It froze again 15 minutes later.
Acting on a hunch, I improved the caching (Cloudflare CDN) to reduce server load. The site has been running without issue for three hours now, which hopefully means the acute incident is resolved.
I still don’t know what went wrong. The server process was still running, but was returning some kind of error response with no log output. I will work to understand the root cause and also find ways to mitigate the issue faster should it happen again.
