As u might have noticed all servers are currently down. The steam servers are overloaded so we can't even download the update anymore at this point, and it seems to get worse every second. Like 0.01% of the dedicated server download takes about 30 minutes, and people that have completed it are reporting crashes anyway.
So... we're probably looking at entire reinstalls of all servers and a redo of some mods/plugins (source, metamod etc.).
That means we are facing some serious downtime here, I think we will probably back up tomorrow evening (CET) at the earliest.
Nice work Valve, That DLC better be damn good!
