- 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:

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.
