As of today, siberian servers are also down, following the moscow ones (post here).
Though, when I'm trying to spawn a new siberian server, the error message is different from what I see when spawning moscow serv:
Requested location is unavailable or overloaded. Please try again later or use another location -- for Siberia;
Unable to handle request -- for Moscow.
I know you're working on fixing the Moscow servers, hope siberian ones will be fixed aswell.
