SmurfKinG, did you try to ping server.war2.ru?
I just trying to ping your ip from both the server and the backup now, it works fine for me.
Not so good latency (150-200 ms), but it's stable.
I'd say that looks like a global routing problem between you and server (both servers?)
Try to ask your ISP. I'll try to ask hosting support, but you say that you have the same problems with both servers...
Also try when servers are unreachable:
1. to run ping server.war2.ru and ping backup.war2.ru
2. to run tracert -d server.war2.ru and tracert -d backup.war2.ru
3. to run ipconfig /all
And copy and paste the result to me in PM
