During the Tuesday, 5 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:

  • Data centre routing: a configuration change will be made to routing between data centres and the rest of campus. Starting from 8 PM, a number of brief interruptions are expected, during which time all services hosted in the data centres will be unreachable. In the event of unforeseen problems, longer outages are possible.

  • 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.

    • DNS

    • DHCP

    • NTP

    • RT

    • Web proxies
