During the Tuesday, September 6th 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:

  • File servers: previous attempts to update the software on the jackal.ru.ac.za server have not been successful, so a further attempt will be made to update it.  Software will be updated on the gnu.ru.ac.za server.  It will not be possible for students or staff to log in to public labs oraccess files stored on jackal or gnu during the outage.  It is expected that both jackal and gnu will be unavailable for the entire evening.
    • Correction, 6 Sep 2016: it will be possible to log in to public labs, but it is not possible to save files on jackal or gnu. Saving to USB flash disks or external hard disks is possible during the maintenance.
