During the Tuesday, March 5th 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:

  • iPrint: software on one of the iPrint servers will be updated.  We expect an outage of an hour affecting printing to all iPrint printers.
  • Distribution routers: a link between the distribution routers for the main campus sector (the area enclosed by Lucas Ave, Somerset St and Prince Alfred St as far as the Library and Psychology Building).  All network services in that area may be disrupted at times for a period of up to two hours.
  • 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
    • 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
    • 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)
  • Wireless links: software on point-to-point wireless link devices will be updated. This will cause network outages (including IP telephones and Wi-Fi access) of up to ten minutes in the following buildings:
    • 1 and 3 On Luke
    • 7 Croft St
    • Duna Libraries
    • Joza Youth Hub

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.
