Mail Interruption Sunday, March 16

Mail service on Central UNIX (AIX/HP) will be interrupted on
Sunday, March 16 from 8 a.m. to 5 p.m., to accommodate
switching mail services back to the production machine from
the temporary machine. Incoming mail will be delayed during
the upgrade, and usersŐ incoming mail folders (inboxes) will
not be accessible. There should be no lost mail during this
interruption, which will last from 8 a.m. until 5 p.m.

NOTE:  This is an extension of the normally scheduled Sunday
       down time of 8 a.m. to 12 p.m.

All users who use Central UNIX mail service will be
affected. Users who log into the system will appear to have
empty inboxes during this time period only.  They will be
able to read only saved mail. They may send mail, but mail
to other users within the cluster is discouraged, since it
will be delayed.  Users of POPmail (Netscape and Eudora) can
neither send nor receive mail.

On Sunday March 16, a substitute computer will be removed
from service and the normal mail server will be put back
into service.

Office Vision users sending mail to the UNIX system during
this time may receive a warning message that the mail to the
UNIX system is delayed, but the mail will eventually be
delivered.

Additional downtime is to be expected on yet to be
determined days from March 25 through March 29 during
quarter break.  The system and all services associated with
it will be totally unavailable during this time.  More
information will follow in a separate article in the near
future.
