“Once in a while we have to do some extended work to our datacenter, and sometimes it takes longer than it should due to unintended consequences,” Matt Firor wrote via Bethsoft’s Gina Bruno this afternoon. “Today’s downtime was required to upgrade parts of the datacenter in preparation for Morrowind’s launch. It took longer than we thought because we ran into a couple issues relating to network security that was preventing different parts of the network from talking to each other. It’s never fun for anyone when we have extended downtime like this, but it’s always for a good reason. We try to schedule downtime at the least populated time for the game (remembering that ESO is worldwide and downtime will always inconvenience some players, no matter when it happens). We always strive to get everything back up and running quickly and do everything we can to keep maintenance windows as short as possible.”
The explanation hasn’t stopped EU players from pointing out that because EU maintenance is done on ZeniMax’s NA schedule, even a regular-length downtime can creep into prime-time for some EU players.
