I keep getting server timed out. I can connect to other servers but not yours and I see from my friend bear that the  population keeps dieing. Is there a server issue?

Same here, only I can't logon to any servers.

Guys, there was a server platform update on 29th that affected the PC version of all the COD games for most of the day.

The PF server has been running normally since then with the peaks/troughs of player numbers as expected.
On refreshing my favourites list, there are fewer and fewer servers running WaW.
If you still have issues, get onto our TeamSpeak channel and one of the members may be able to talk you through it.
