Blizzard and Sony Online have revealed over the weekend that Ivan, last weeks hurricane to hit North America, has caused temporary interruption for their respective MMORPG, World Of WarCraft and Star Wars Galaxies.

Over the weekend Blizzard updated the official World Of WarCraft website informing its U.S. beta testers of what had happened: "the datacenter complex in Virginia that is being used to host the World of Warcraft beta test was hit and damaged by a tornado. Because water was leaking into the building in which our servers were located."

The same complex houses Sony Onlines Star Wars Galaxies servers and people may have experienced similar problems.

Blizzard said a team of network engineers was already sent, and they expect the problems to be resolved today or tomorrow, depending on when the hardware "dries out."
