During the Tuesday, November 4th 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:
  • Web proxy servers: software on the web proxy servers will be updated, and a configuration change will be implemented. Access to the web may be affected at times throughout the maintenance window.
  • Struben data centre hosting rack power: power distribution within the hosting rack in the Struben data centre will be upgraded. All servers within the rack will experience a network outage for approximately 30 minutes. Servers which do have redundant power supplies (listed below) should not lose power, but will only have a single power supply connected while each of the two power distribution units are replaced, and thus are at risk of an unplanned power interruption.
    • vault.amm
    • deepsight.coe
    • RUBI servers and NAS
    • RUCUS
    • ILAM Greenstone and file storage
    • SAIAB DR server

    Servers which do not have redundant power supplies (listed below) will be shut down for a period of approximately 30 minutes.
    • ILAM tape library
    • COE schools server
    • COE storage server
    • Albany Museum Specify server

    The two Maths cluster servers will be shut down for a period of approximately 90 minutes while work in the hosting rack is completed and the servers are moved into the hosting rack.
  • Server software updates: software on the servers which provide the following services will be updated, resulting in outages of approximately five minutes per server:
    • DNS
    • DHCP
    • NTP
    • RT
    • Web proxies
    • Registration system
    • Incoming e-mail

  • Firewalls: software on the firewalls which connect the Internet to the campus, SEALS and public networks will be updated. As the firewalls operate as a redundant pair, no noticeable outages are expected during this maintenance.
