Hoster issues and server hickups.
Just a FYI, we are looking at new hosters right now. The current level of support for these guys is horrable, most times the responce in a nutshell is “deal with it”. Over the past couple of days we have hit the disk quota, it seems, hence the “disk quota” error that some of you may have seen. Currently its working fine right now.
As for what this will affect when we move? Not really anything on your side other than less lag. All we will have to do is point the tbuminecraft.net address to the new server once we have it.
