[dns-wg] f.root-servers.net unreachable for a few days?

Hello,

I noticed that f.root-servers.net is unreachable via IPv4 from my test locations (most of them in Germany).
Relying on RIPE ATLAS [1] I'm pretty sure I'm not alon with this "problem".

A traceroute from my home DSL connection (DTAG, AS3320) shows that packets are surprisingly routed to somewhere in Pakistan and never get answered.
Also Port 53/UDP/TCP is unresponsive.

Has something happened to the F-Root instances in Europe? Or has the IP address changed?
