When you shut down for your maintainence, what exactly are you doing???? Just curious, cause it seem as if for some reason when I play in CL the movement of my wizard skips more than anywhere else in the game.... When I say skip, What I mean to say is it seems to have a lag time and when moving around it skips and is not smooth. I have checked and rechecked my settings and connection and as for as I can tell nothing has changed on my end...
For the most part of the maintance all they're doing is restarting the entire network as to refresh the ram and virtual memory. its quite common to be forced to restart a network, as heavy loaded as this one is, often due to the strain on the computers, it also lets them have a break and cool as cooling systems can only do so much.
gimme a break, gimme a break, break me off a piece of that kit-kat bar. :P
