                  W92 Computer Room
                 Tuesday, April 6th commencing at 11pm


---------------

As you may be aware, the uninterruptible power system (UPS) supplying 
the W92 computer room was damaged last Friday (April 2nd) when a small 
fire forced an emergency shutdown.  Although most services were 
restored on Friday, there is lingering damage to the power system that 
needs to be repaired as soon as possible.

Most of the repairs can be facilitated while power is on-line, but 
unfortunately not all of them.  We will therefore be scheduling some 
number of W92 computer room shutdowns to repair equipment damaged on 
Friday and to rectify some on-going issues that contributed to the 
failure.

The first of these shutdowns is scheduled for this Tuesday night (April 
6th) starting around 10:30pm.  We will be powering down the room at 
11pm and we expect to begin the shutdown of services around 10:30pm.  
We will shutdown the most critical services last and restore them to 
service first.  We expect to have power restored to the room by 
midnight with most services operational before 1am (Wednesday, April 
7th).

Services affected, include:
      E-mail Storage (Post Office servers)

      web.mit.edu (MIT’s main web site)

     Significant portions of the Athena AFS file system will be 
unavailable.

Note:  We do not expect to have to shutdown our external connectivity.  
MITnet's connection to the outside world should remain operational 
throughout the outage.

Further notifications related to this outage will be posted to 
<http://is3down.mit.edu> . The is3down site is the home of the 3DOWN 
Services Status page, which is frequently accessed via 
<http://web.mit.edu/3down>.  As web.mit.edu will not be available 
during this outage, please access the 3DOWN site via 
<http://is3down.mit.edu>

In closing, thank-you for your patience and understanding during this 
important planned outage.  Please assist us in sharing this information 
within your Department, Lab or Center.  Should you have any pressing 
questions or concerns, please e-mail <network at mit.edu>
