2013/09/03 - Scheduled maintenance: various services
During the Tuesday, September 3rd maintenance window, maintenance work affecting a number of services will occur, starting at 5:30 PM:
  • DNS/DHCP/NTP server software updates: software on the two servers which provide the DNS resolution, DHCP and NTP services will be updated. You may notice that network applications respond slower than usual during those times when the DNS server which is your PC's primary DNS resolver is unavailable. DNS queries will be answered by the secondary DNS resolver, but only once the request to your PC's primary DNS resolver has timed-out.
  • Core router software update: the software on one of the two core routers will be updated. No noticeable outage is expected as all network traffic should be handled by the other core router.
  • Distribution router software updates: the software on all of the distribution routers in campus (except for the data centres and west campus sectors) will be updated. All buildings will experience a network outage that we expect will last between 1 and 20 minutes (depending on the way in which each building is connected to its distribution routers) and will cause all network services (including IP telephones) to be unavailable.
This maintenance work is being undertaken in the ITSC-approved scheduled maintenance window, and should be completed before midnight. More information about maintenance windows and maintenance periods.
This maintenance work has now been completed.
