During the Tuesday, 7 June 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:

  • TENET router replacement: TENET staff will be replacing the Makhanda router in the SANReN network.  This router connects RU and other Makhanda research/education sites to the SANReN network and in turn to international research and education networks and the Internet. Brief interruptions in Internet connectivity are expected. Unforeseen issues may result in longer interruptions.

  • 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

    • 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)

    • File servers/home directories (gnu, serval, studentfiles)

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.
