SUBJECT:

Communication Outages This Summer

Administrative Computing and Telecommunications (ACT) is remodeling and
expanding its space in the Central Utilities Building, the core of UCSD's
communication systems. We are also upgrading the air-conditioning and
power to improve the reliability of the services there, particularly
of the campus data communications network.

This work will require that we schedule some outages. We do not expect the
outages to last more than an hour or so, and we will schedule them during
the "wee hours of the morning." During these times, much of the data
communication both on- and off-campus will be interrupted and the cc:Mail
server will not deliver messages. The Ericsson telephone system and the
800Mhz radio system should continue to work normally.

The exact timing of these outages is dependent on the progress of the
construction work, but the first shutdown will occur in July, probably
around the 10th, at midnight. In addition, several smaller shutdowns of
individual pieces of equipment are likely.

We are sending this advance notice now, so that you will have as much
awareness as possible prior to the events described above. We will
announce major outages to the entire campus; minor outages will be
announced to the campus-outages@ucsd.edu email list.

If you require further information, please call ACT's Help Desk at (619)
534-1853.
