Seems that i had a little downtime the last couple of hours. Well, not really down, but totally overcrowded. My current server configuration was not able to manage the traffic, and had a little breakdown. It didn`t react anymore.
I have restarted the server now, and am currently in the process to tweak a few things at the server to compensate that. Fingers crossed that it will help. When not i may need to upgrade the hardware. But i hope that this is not necessary.
Sorry for the downtime folks.
