2022/04/19 - Scheduled maintenance, 19 April

During the Tuesday, 19 April maintenance window, maintenance work will affect certain services, starting at 7:30 PM and being completed before midnight. The following work is planned:

  • Distribution routers: software will be updated on the routers serving the university data centres.  All services hosted in data centres will be affected for at least brief periods, but possibly for as long as an hour.
  • Firewalls: software will be updated on the firewalls which connect the Internet to the campus, SEALS and public networks. As the firewalls operate as a redundant pair, no noticeable outage is expected during this maintenance.
  • Internet routers: the active and standby routers will be switched to test a new software version. Brief (less than 5 minute) disruption to Internet access is expected.

The last two points had previously been planned to be done on 12 April, but could not be completed then due to load shedding.

This work is being conducted during a minor maintenance period. Should there be a compelling reason why this work should not go ahead as planned, please contact before 3:00 PM on Tuesday.
