Doesn't sound like you've played many mmos. Its been going down during primetime for the US too, so please don't try to make this a "woe are we the Europeans".
You are missing the point. Servers crashing and taking time to come back up is one thing, obviously that isn't intentional even if it is still their fault. The issue is that they're chosen time to deliberately shut down the server to apply fixs seems to be around 9/10am PST which is 5/6pm for Euros.
The other thing is it's pretty hard to excuse poor netcode in this game when the it is a modified version of another MMO that has been live for almost 8 months. You'd expect that to make it smoother than the average MMO launch.
