I’m currently dealing with 522 errors. Having a history of what cloudflare IP’s are having issues and when would be a huge help in getting an internet provider to accept that something might be going on in their infrastructure. I can clearly see some requests come through but it is clear many requests never make it to my server.
I know nothing past my provider on my end is blocking any thing.
If I had data about what IP’s are failing vs which are working and when then the provider would at least have something to work with. But as it is I really can’t tell them much other than provide the list of addresses clourflare outlines as needing access but the provider says they don’t block anything.
