One more, joining for the same issue in Bulgaria. I checked with friends from other countries in the EU, but looks like we are the only ones affected.
I also submitted a support request, so we shall see. (Сериозно, след близо три години игра съм шокирана, колко много сънародници има наоколо, което е странно. Но предполагам, вината е моя, че съм се забила на сървара с французите. XD).
Definitely sounds like a server side issue, or more like the "gateway" to the server itself. If it is a whole region affected, it should not have anything to do with the local providers. VPN can help, because technically it lets you use another gateway, I guess, but it is not really solving the issue.
