503 errors

We've been seeing 503 errors on https://changelog.com starting on March 29th @ 13:40:50 UTC:

We assumed that this was Erlang/OTP 26.2.3, and downgraded to 26.2.2, as captured here: #507 (comment)

Today - April 1st - the 503s re-appeared at 13:22 UTC even though nothing changed with the app:

According to Fly.io app metrics, the app did not return any 503s:

This makes me suspect that there is an issue with Fly.io proxy layer. I have been getting timeout alerts (exceeded 48s) for other workloads that are running on Fly.io, completely unrelated to this one.

Will reach out to Fly.io for more details. FWIW:

• Incident Report for Fly.io - App Logs Delayed

This issue went away on its own at 13:45 UTC, April 2nd:

There have been no 503s reported by the app in this period:

Also, a deploy went out at 16:38 UTC, so it's unlikely to be related to that:

Closing this, it served its purpose.
