During the Tuesday, 1 December 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

    • IMAP e-mail mailboxes

    • Webmail

    • Mailing lists

    • SMS

    • Provisioning (web proxy autodiscovery)

    • 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)

  • iPrint: the print accounting software will be updated.  We expect an outage of an hour during which it will not be possible to print to any iPrint printer.

  • File servers/home directories (gnu, serval) Firewalls: software will be updated on the firewalls which connect the Internet to the campus, SEALS and public networks.  As the firewalls operate as a redundant pair, no noticeable outage is expected during this maintenance.

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.
