Cannot connect to EU#1 but can connect to EU#2 and EU#3 and all US servers

So basically I have this problem, that sometimes cod4 refuses to connect to a server. The strange part is, that I can connect to EU#2 and EU#3 but not EU#1. EU#1 doesn't show up on the server list nor does it connect through console. I used have this a few months ago, but now it started again. Thing is it will randomly start working again and randomly stop working again. Right now it's with EU#1 but it can happen with any one.

Is this a known problem. Any solutions? Thanks

Might be when you ISP change's your IP address, so there might be a connection stuck with your old address.
Try to do a :

ipconfig /flushdns

In a command line box.

I tried that, didn't work though.

Strange thing is, today while I was playing on eu1 i got disconnected so I left the game and opened server list again. And couldn't see eu1; tried console connecting but still it timed out.

I restarted my router and PC and now I can't even see US#1 lol
