Something’s wonky, because it’s not just Cloudflare. One of my personal sites is down that uses nothing but a VPS, and I noticed my Unifi AP disconnect from its controller a little bit ago. Fiber cut? Routing issues?

If that VPS is on DO they're down too cause of CF. Or if you set the resolver on your VPS to 1.1.1.1 that's also down.

Why are digital ocean VPSes down due to a Cloudflare outage? Hoping for a clarifying post mortem...

digitaloceans VPSes weren't down, but there do seem to be routing issues as TransIP can't reach DigitalOcean AMS3 (but it's all coming back now)

Maybe the problem was somewhere on the AMS-IX

My Digital Ocean load balancer went down. I think there's probably some internal routing? Would be interested to understand more.

DO is still up as my machines are still up and accessible.

Huh. My Ubiquiti was reporting WAN link down during this outage. I'm using ATT fiber. I'm wondering if "link down" doesn't mean what I think it means. Now that I check, it says "WAN iface [eth2] transition to state [inactive]". I'm wondering if that means link down or if it's doing service checking.

I actually have a WAN2 configured but not plugged in and it was set to "Load Balancing: Failover Only" ... I wonder if all of my 'connection issues' were software assuming my network link is down and switching interfaces to an unavailable one.

to reply to myself, if you have a second interface configured for failover, it actually tests against ping.ubnt.com. I bet every single time my ATT fiber has "gone out" for a minute or two at a time, it's been bogus.
