Friday December 26, 1997

Electrical "Feeder" Outage Affecting the Entire Campus except the
Computer Center (Building 14).

Starting time of service interruption: Sunrise
Ending time of service interruption: Sunset

What is the Reason for this Service Interruption?

        Power to the entire campus  is being cut by P.G.&E.  Work is
        being performed during daylight hours.

        NOTE:  If work cannot be completed on Friday, December 26, 1997,
        P.G.&E. is reserving the right to also use daylight hours on
        Saturday, December 27 and Sunday, December 28, 1997.  Users can
        check on the work in progress on Friday afternoon by calling the
        Utilidor recorded message at 756-6808 as the requirements of the
        outage change.

Who is Affected by this Service Interruption?

        If all goes according to plan, Cal Poly Modem Pools, Computer
        Center computer systems (Central UNIX and the mainframe), and
        access to the Internet should remain up.   However, there is a
        possibility that there could be a service interruption as
        described below.

What Services will be Affected and How?

        All buildings with the exception of the Computer Center and
        those noted on the Utilidor outage pages
        (http://www.facsrv.calpoly.edu/utilidor/) will be without power
        for this time period.  The Computer Center will be switched to a
        generator for the duration of the outage and switched back after
        the outage.  During the switching to and from the generator, the
        Computer Center systems will be powered by a UPS
        (Uninterruptible Power Supply) system which should allow the
        systems to remain up without interruption.  The Cal Poly modem
        pools and access to the Internet should also remain up during
        this time period.

        ONLY IF THERE IS AN UNANTICIPATED PROBLEM will Computer Center
        services be interrupted.   If the time taken to switch to and
        from the generator exceeds the limitations of the UPS, there is
        a potential for an outage of long enough duration to bring the
        systems down and bring them back up once power is restored.  In
        that case there could be an interruption of the following
        services including, but not limited to

	Service                     How Users will be affected
	OpenMail and OpenTime       OpenMail and OpenTime may be
                                    unavailable.  The Web interface for
                                    OpenMail may also be unavailable.
                                    All incoming mail from outside
                                    OpenMail will be delayed for the
                                    duration of the outage.
	World Wide Web              Users may not see pages housed on
                                    the Cal Poly central web server
                                    (www.calpoly.edu) or links to pages
                                    that are referred to off of the
                                    central web server.
	Gopher                      Users may not be able to access
                                    documents on the Cal Poly gopher
                                    server. This includes pages
                                    referred to by other gopher and web
                                    servers.
	UNIX Mail                   PINE, Elm and UNIX mail on Central
                                    UNIX may not be available
	POP Server                  Any pop client (Netscape, Eudora,
                                    etc.) pointing to pop.calpoly.edu
                                    will fail to connect.
	SMTP Mail Server            Any mail client sending mail via
                                    smtp.calpoly.edu or
                                    mail.calpoly.edu may fail to
                                    connect.
	Central UNIX user login     Users may not be able to connect to
        sessions                    polylog1 or rodin.
                                    NOTE: cymbal, flute, harp, trumpet,
                                    tuba, and violin all point to
                                    polylog1.
                                    NOTE: NEVER use "monet" as a site
                                    to log into. Logging into it may
                                    result in none of your files being
                                    available.
	Xterminals                  Xterminals which are served via the
                                    Central UNIX cluster will be down.

What is the Expected Outcome of this Service Interruption?

        This service interruption is required by P.G.&E..
