During the Tuesday, 27 February maintenance window, maintenance work will affect certain services, starting at 5:30 PM and being completed before midnight. The following work is planned:
Distribution routers: the routers serving the university data centres will be replaced with newer models. It is expected that access to all services hosted in university data centres will be interrupted for a period of less than ten minutes. In the event of unforeseen problems, it may take up to two hours to revert to the previous routers.
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.
This work is being conducted during a minor maintenance period. Should there be a compelling reason why this work should not go ahead as planned, please contact support@ru.ac.za before 3:00 PM on Tuesday.
