2019/12/03 - Scheduled maintenance, 3 December

During the Tuesday, December 3rd maintenance window, maintenance work affecting a number of services will occur, starting at 5:30 PM and being completed before midnight.  The following work is planned:

  • IP Telephones: all phone services will be unavailable for a period of around 15 minutes.  After that time, the university's telephone system will no longer require that one dial a zero to get an outside line before dialing any external number.  From then on, please dial all external numbers without adding an extra zero, just as one would when dialling from your mobile phone, or from your landline at home.

    Internal calls and incoming calls originating from outside the university will not be affected by this change.  This change will apply when sending faxes using the RightFax service.
  • TerminalFour: software on the server hosting TerminalFour will be updated. We expect an outage of two hours during which time it will not be possible to change content managed by TerminalFour (already published web pages will still be accessible).  This work could not be completed in the November 5th maintenance window, so it will be attempted again.
  • Request Tracker (RT): RT software will be upgraded.  We expect an outage of two to three hours, during which time it will not be possible to access the RT web interface.  E-mail messages will be processed once the upgrade has been completed.
  • Server software updates: software on the servers which provide the following services will be updated, resulting in outages of up to 15 minutes per server.
