2015/06/02 - Scheduled maintenance
During the Tuesday, June 2nd maintenance window, maintenance work affecting a number of services will occur, starting at 5:30 PM and being completed before midnight. The following will occur:
  • Network printing services: printing accounting software will be upgraded, which will take about an hour. During times when the printing servers are down, print jobs will be rejected with an error message. During other times in the upgrade, print jobs will be held, then printed later. Staff and students should not reprint if their print job(s) isn't printed immediately unless they receive an error indicating that their print job couldn't be queued.
  • Distribution routers: software on distribution routers for the main, mid and St Peter's campus sectors will be updated. In the main and St Peter's campus sectors, a network disruption of less than a minute is expected. In the mid campus sector, this will result in a network outage (including IP telephony) of approximately 15 minutes.
  • Wi-Fi access: a configuration change will be made to all Wi-Fi access points on campus which will cause each of them to reboot. Wi-Fi access will be disrupted for about five minutes.
  • 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:
    • DNS
    • DHCP
    • NTP
    • RT
    • Web proxies
    • Registration system
