During the Tuesday, November 1st 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:

  • 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
    • Registration system
    • Incoming e-mail
    • Outgoing e-mail
    • E-mail mailboxes
    • Webmail
    • Mailing lists
    • SMS
    • Apple Software Update Server
    • Provisioning (web proxy autodiscovery, telephone provisioning)
    • Wi-Fi and VPN authentication
    • CHERTL Evaluation Assistant
    • Network graphs
    • Guest network access
    • Network monitoring
    • Terminal Four content management system
    • RU Single Sign-On system
    • Main web server (www.ru.ac.za, etc)
    • University administration and meal booking systems
    • SEALS Library consortium services
    • Network printing services (iPrint / PaperCut)
    • Home directories (gnu)
  • Distribution routers: software on the distribution routers for the west campus and main campus sectors will be updated.  Brief outages are expected, during which time no network services (including IP telephones and Wi-Fi access) will be available within the affected sectors.
  • Storage systems: software on storage systems will be updated.  No outage is expected, though an unexpected failure during the upgrade would cause an outage affecting almost all services.

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. More information about maintenance windows and maintenance periods.
