From WoW EU site.European Maintenance Times Changed
Daliniya, 04/05/2005
In response to player input, the European weekly maintenance hours have been changed. Starting May 11th, Europe’s new maintenance window will be on Wednesday mornings from 5:00 am until 11:00 am CEST (Central European Summer Time). If a patch is applied during maintenance, then the window will be from 3:00 am until 11:00 am CEST.
This week’s maintenance will go ahead for the last time on Friday morning from 5:00 am until 11:00 am CEST.
Looks like they have finally listened to reason and moved it from Fridays, which is such a good idea...
