There was no UDP connectivity from any of our servers for ~10 minutes, but TCP was working fine, I could SSH into them.

Even Hetzner's Robot interface was down.

Very interesting. That would suggest to me that all traffic is passing through a stateful device vs. direct connectivity from a router. Routers can give simple bandwidth metrics. A stateful device or mirrored ports to a netflow analyzer would be required to create detailed connection logs though mirrored ports wont break state such as UDP virtual tables being full. Are they doing detailed logging of traffic?

> We are currently experiencing a fault with UDP forwarding.

Exactly right.

From our logs, the main outage went from 21:01 to 21:10 UTC.

It seems to be back up. I can access https://console.hetzner.com/ now, and our VPS are back online.

Yeah first time in 6 years being with them that I've had an outage of this scale. Cloud VMs and Dedicated servers all down / intermittent

Everything went down but seems to have recovered now.

They sent out an email about raising their prices earlier today. Perhaps it was everyone running for the doors.
