Ending time of service interruption: 5:00 PM
The Mail Service Machine will have been upgraded to increase its throughput. Specifically it is scheduled to have both hardware and software upgrades applied. These upgrades include
- HP-UX 10.10 to HP-UX 10.20 which includes
- Sendmail 8.x
- 64 bit application addressing support
- Support for 100BaseT Ethernet Adapters
- Installation of 100BaseT Adapters
- Replace 2 PA-7200 processors with PA-8000 processors (roughly a 2.4 fold performance increase in CPU power).
Because of these upgrades, and the down time required to perform them, Mail Services were moved to a temporary site for several weeks. When the upgrade is completed, the service will be moved back to the original site.
All users will be affected. In order to preserve data integrity, users will not be allowed to login to the system during this time.
All services will be unavailable during this time period.
Revised by: George Westlund (gwestlun@calpoly.edu)There should be no lost mail as a result of this outage! However, incoming mail will be delayed on Sunday, April 6.
Mail which cannot be delivered from other systems during the service interruption period will be queued by the sending machine. Most machines queue their outgoing mail for at least three days, trying every half-hour or so to deliver to the target address. If the target address remains unavailable for longer than this time period, mail is then bounced back to the sending user (not likely during this outage because of its limited duration). Some machines also send a warning message to the sender indicating that the mail is delayed and that the sending system will continue trying until its maximum waiting period is over.
