Anyone else having IPv6 issues with Cloudflare?

Question

Got a bunch of pings from updown.io saying there are IPv6 timeouts to sites using cloudflare, they seem to be intermittent for about the past 30 minutes, nothing on the cloudflare status page though.

adrien from updown.io here.Sorry about this, I still don't have any answer or explanation from Vultr or CloudFlare at this point. Most likely cause IMO is that CloudFlare (accidentally?) blocked one or many big ranges of IPs belonging to Vultr (and maybe some other providers as people seems to say Vultr was not the only impacted). I noticed during the incident this morning for example that I could ping CloudFlare IPv6 (ICMP) but not connect through TCP (port 443). So this sounds more like a firewall than a routing issue from what I could see.I'll update once I have anything else in https://status.updown.io/issue/1e196616-1368-43a0-8c04-82cff.... For the moment I'm keeping the mitigation in place just in case.If you have more details about this from CloudFlare or elsewhere I'll be happy to hear it :)

I have a personal monitoring system (uptime kuma) running on Hetzner (Germany data center) and since around 5am UTC today I am seeing intermittent timeouts only on services proxied by cloudflare so not just Vultr affected it seems&hellip;

Yeah, I just woke up to some alerts, too. Sometimes I get the feeling people don't take IPv6 seriously!
