This is the information we're getting from Network54:
Friday: Physically moving the equipment to a new rack. Nothing will be plugged in for a while, thus the hard downtime. Expect the site to be truly down all day. It should only take four hours, with only about one to two of complete downtime. I think we will have an extra server just sitting there with a plain maintenance page, but no read-only. So we are hoping for only a couple hours, but packing food, etc. in case we are there all day.
If you want to have a cleaning buddy, today would be the day to make alternative arrangements, e.g. email, IM.
They are unplugging and moving the servers (the computers that hold all of N54) to a new server rack. Picture of a server rack (for non compy techy people, i.e. Script )
