2018/08/07 - Scheduled maintenance, 7 August

During the Tuesday, August 7th maintenance window, maintenance work affecting a number of services will occur, starting at 5:30 PM and being completed before midnight. 

A number of network outages are expected.  If devices are not able to connect after the maintenance window, please restart the device in question, and if the problem persists, report to the service desk via or 046 603 8288.

The following work is planned:

  • Distribution routers: software on the distribution routers for all sectors of the campus will be updated.  Brief outages are expected, during which time no network services (including IP telephones and Wi-Fi access) will be available within each sector.
  • Wi-Fi controllers: software on the controllers managing Wi-Fi access points on campus will be updated. Wi-Fi access across campus will be unavailable for around fifteen minutes.  Approximately half of the access points will need to be rebooted a second time, resulting in a second outage of around fifteen minutes in areas served by those access points.
  • Server software updates: software on the servers which provide the following services will be updated, resulting in outages of up to 30 minutes per server:
