Recent 7.0 issues

[Jibbatwinkers]

Jibbatwinkers here, owner and operator of the Zebuxoruk server. The last few days/7.0 updates I've ran into a rather serious problem. After a seemingly random amount of up-time the server simply stops letting people zone in. Alot of time it's only the nexus and sometimes It's all zones. Being on the lan the server is on, it seems like I can get on during these "down times" for my other players. The next thing I'm going to try is taking away all my static zones (nexus is/was static) maybe that is the issue I'm not sure.

Info:
-I'm running 7.0800 and its been happening with the two previous updates as well.
-None of my zone servers crash, they just stop letting people in.
-People have reported getting 7017 errors and "This zone is not availible" errors.
-Because I'm able to get on, I'm thinking it might be a new router issue, but I havent figured out why it would start up at random times after a fresh boot.

Any ideas? My players would be most appriciative if we could get this solved.
