Wow. Ninety-one full hours? A planned outage for ninety-one full hours? That's absolutely remarkable!

Hello everybody,
Just in case you haven't already seen the announcements:
The campus computing group - IS&T will be moving all the major campus servers and systems to their new, greatly improved facility at the corner of Hearst and Oxford Streets in June.
There will be downtime for all servers including Socrates and Calmail.
They have already begun moving equipment and systems, but the major down time will be near the end of the month.
The basic schedule is as follows:
Calmail may be moved as early as June 18 - specific downtime to be announced.
Friday June 25 noon to Tuesday June 29th - 7am EXPECT ALL SYSTEMS TO BE DOWN
Information on the move (including a gallery of construction photos) has been broadcast on ITnews (online version of the Berkeley Computing and Communications newsletter) at: http://inews.berkeley.edu:7077/channels/iNews/dcmove/
A timeline for the move schedule is at: http://dcmove.berkeley.edu/schedule.html
My office recently moved to a new location. Computer systems, including email, were moved over a period of a few weeks, there were hardly any outages and those outages lasted for well under an hour.
This is the elusive "two nines" standard that they talk about at all the High Availability Computing conferences.

Still, think of all that undelivered spam! Will humanity ever recover?
