During the Tuesday, 16 September maintenance window, maintenance work will affect certain services, starting at 5:30 PM and being completed before midnight. The following work is planned:
Server hardware updates: the servers which provide the following services will be migrated to new hardware. Disruption should be minimal as multiple servers provide each service.
DNS
DHCP
NTP
Access switches: the network switches in the buildings listed below will be replaced. All network services (including Wi-Fi and IP telephones) will be disrupted in those buildings for up to 90 minutes.
Barratt Lecture Complex
Chemical and Pharmaceutical Sciences (north side)
Institute for Nanotechnology Innovation
Core router: one of the two core routers in the campus network will be replaced with newer hardware. No noticeable outage is expected as all network traffic should be handled by the other core 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.
