Same here on Moogle. Started at about 6 p.m.(ish) and keeps dc'ing me every 30 secs - 2 mins. Tried 2 different PCs in case one of them started having issues with anything. But since one's running Win7/64 (wired) and the other Win10/64 (on Wi-Fi) were getting the same results, I tried to connect via my phones mobile connection (which worked great in the past) but to no avail.

I'd rather not have a second datacenter like chaos, cause it'll increase duty finders queues even more.

Moving Chaos would be even more dumb since it's already in one of 7 major datacenters in Frankfurt.
The highest chance of them being the DE-CIX7. (https://de.wikipedia.org/wiki/DE-CIX)
Cause it's the one closest to KDDI Germany (who's the one providing the ip-adresses for Chaos).

Somebody with enough time should drive there and knock really hard on the door to wake them again. They've probably just fallen asleep
(I would do it myself but I have to go to work today xD)
