During the Tuesday, 2 July 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:
ZENworks Configuration Management: the service will be migrated to a new server installation. During this maintenance, we expect that it will not be possible to login to public lab and multi-user desktop PCs for a period of approximately 1.5 hours.
This work was begun in the previous maintenance window but could not be completed then.
Access switches: software will be updated on the network switches in the buildings listed below. All network services (including Wi-Fi and IP telephones) will be disrupted in those buildings. Services are expected to be restored in each building within 30 minutes.
Facilities and Infrastructure Division offices
Literary Studies in English Building
5 Prince Alfred St
Drostdy Barracks (Linguistics and Applied Language Studies)
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:

Web proxies

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.
