2024/01/23 - Scheduled maintenance, 23 January

During the Tuesday, 23 January maintenance window, maintenance work will affect certain services, starting at 5:30 PM and being completed before midnight. The following work is planned:

  • Firewalls: a configuration change will be made to the firewalls which connect the Internet to the campus, SEALS and public networks. This will involve a brief (< 1 minute) Internet outage. All established TCP connections will be disconnected and applications will need to reestablish their connections.
  • Wi-Fi: the controller software which manages Wi-Fi access points across campus will be updated. It is possible that eduroam Wi-Fi service across campus may be unstable for some hours during the evening.
  • Internet edge routers: the software on the two Internet edge routers will be updated. No noticeable outage is expected as all network traffic should be handled by the alternate router while each router is updated.

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.
