Every since yesterday when the random 503 errors were appearing, larger documents have started to hang sporadically. Is any one else seeing this? Cloudflare Status doesn’t mention anything (but they didn’t mention the increased error count yesterday either, so that’s really not saying much).
Any documents larger than ~1mb seem to be affected, binaries (e.g. images) seem to work. It’s not perfectly reproducable, but it happens across multiple accounts with different origin data centers, and for people in different countries with different CF access points, so it’s unlikely to be something local or related to specific infrastructure.
Reducing document size seems to help, but unfortunately isn’t always an option (e.g. using Symfony forms, complex and detailed forms will produce multi-megabyte HTML).
