First reported yesterday, still trying to identify the pattern / root cause.

Problem

Certain inscriptions are not loading, the connection stays open until a 524 error is returned. So far it seems to be some of the more recent ones, e.g.

When queried with curl each returns after ~1-2min:

<html>
<head><title>524 Origin Time-out</title></head>
<body bgcolor="white">
<center><h1>524 Origin Time-out</h1></center>
<hr><center>cloudflare-nginx</center>
</body>
</html>

Certain inscriptions are still loading, but seems to be hit or miss. This one seems to work:

But this lower number one does not:

But this one does?

Fix Attempts

  • tried redeploying the site, still seeing the same issue after.
  • manually inspected the function logs, no errors
  • manually inspected the KV data, seems consistent

Next Steps

  • remove non-V2 KV references, then redeploy site (part of Some cleanup and additions #29)
  • KV -> durable object conversion for promise race condition
  • verify traffic with indexer temporarily paused
  • add banner to loading page - we're working on it!

2023/04/30 1600: issue appears resolved with no additional actions, further testing ongoing, suspect it's a problem with indexer and high-volume traffic
