During the Tuesday, 26 November maintenance window, maintenance work will affect certain services, starting at 5:30 PM and being completed before midnight. The following work is planned:
Firewalls: software will be updated on the firewalls which connect the Internet to the campus, SEALS and public networks. Due to an issue encountered with the previous versions of software on the firewalls, a brief interruption to Internet access is expected when we switch between the firewalls: applications will need to reconnect and any downloads in progress at the time will be aborted and will need to be restarted.
Distribution routers: software will be updated on the routers serving all buildings in the areas listed below. All network services (including Wi-Fi and IP telephones) may be disrupted in those areas for up to 30 minutes.
Main campus: all buildings in the area within Prince Alfred St, Somerset St and Lucas Avenue, up to and including Biological Sciences Building, the Library and Psychology
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. Work is expected to take 30 minutes.
Internet edge routers: the software on one of the two edge routers will be updated. No noticeable outage is expected as all network traffic should be handled by the other edge router.
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.
