Update: it appears that the outage of several Microsoft services was not related to the power outage. http://windowsteamblog.com/windows_live/b/windowslive/

Per the San Diego Gas and Electric web site, power has been restored to the majority of customers.

The San Diego area (including parts of Mexico and Arizona) are experiencing a large power outage due to a problem in a high voltage transmission line [1]. It may take until Friday for power to be restored. As a result, expect various internet outages to follow as UPSs run down.

Currently, it appears that MSN.com is at least partially down, and Hotmail.com (aka mail.live.com) is coming up with a home page but after logging in the connection fails. It is not clear if these outages are related to the power outage, but both sites do host some assets in the San Diego area.

Right now, there are no reports of wide spread routing failures.

If you do live in the area, and are still able to read this: Turn off air conditioners and it is best to stay off the roads as traffic signals are failing. Go to bed, get some sleep, and hope that things will be better in the morning as you get up ;-).
