I'm not 100% sure what's going on also. Took a look at the z8 forum, some guy created a thread about it and there are a couple of people saying they have this problem too. Not to mention there are people here on MPGH that are saying the same as well.
Couple of people are also saying how they can't log on at times.

and cant join any channel . so i think the server will be down soon for a whil xD
