Regarding the Internet outtage this weekend. This is the full message from Academic Computing:

The Computer Services Center (CSC) power distribution system has been reviewed
by electrical engineers and other power specialists, who require full control of
the Center's electrical system to make critical changes on Saturday, April 8th,
during the hours of 6:00 AM to 6:00 PM.

All computers and network links that are located in or routed through the CSC
will be down during the outage.  This includes all services hosted through the
CSC, including PAWS/Banner, Hospital Systems, Internet, Library systems, email,
and the dormitory networks. Because of the dependency of computers on
centralized networking services, even your individual office desktop computer
may be inoperable or have limited functionality during this outage.

The CSC is aware that this may cause significant difficulties for individual
users and departments, including Saturday classes. However, if these changes are
not completed, there is a major risk that the Center might in the future lose
power in such a manner that data and hardware would be damaged, with resulting
extended service outages. This particular time slot was selected to minimize
disruptions to weekday University business, but also permit access by the
electrical personnel to support services and electrical supplies they will need
during the outage.  We have already had substantial preparatory work done in a
non-disruptive manner, but these final stages require an outage.

CSC staff will attempt to return full service as soon as possible and earlier
than 6PM if at all possible, but we have been advised by the electrical
engineers that the full outage window may be needed.
