- During the Tuesday, 29 November maintenance window, maintenance work will affect certain services, starting at 5:30 PM and being completed before midnight. The following work is planned:
Access switches: software will be updated on the network switches in the buildings listed below. All network services (including Wi-Fi and IP telephones) will be disrupted in those buildings. It is expected that work will take around 30 minutes per building.

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 was previously planned for 1 November but could not be completed then due to an issue that caused an outage. That issue was investigated and fixed on 8 November so minimal impact is expected now.
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.
