    • File servers/home directories (gnu, serval, studentfiles)

  • 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.

While we try to publish a list of all service-affecting work here in advance, the list should not be considered exhaustive and other low impact work may also be undertaken during the maintenance window.

This maintenance work is being undertaken in the ITSC-approved scheduled maintenance window.
