Okay, some updates from hando:
IPB managed to get the boards working somehow, however, terribly slow with a lot of timeouts (as you might have seen if you visited during the online-time).
They think the server is having serious problems - however, the server is not a dedicated one so hando can't do much.
At the moment, hando tries to fix everything with the server company, if that doesn't work out, he'll probably move to one of my server. That might take a while, but gp32x.de will be back, don't worry.
With new features (like developer blogs, etc.)
