Tomorrow we will have an outage of 90 minutes from 4p to 4:30p 5:30p (Pacific Time) as we perform some hardware upgrades. At the beginning of this outage (the first five minutes), blogger.com will appear completely inaccessible. Following this, a status message will appear for the remainder of the 90 minute outage during which time users will be unable to update their blogs.
Update: The maintenance is now complete and took only 35 minutes. Blogger should be back to normal.
