On Monday, 17 February, maintenance work affecting SEALS Library services will occur, starting at 10:30 AM. Catalogue, issuing and WAM proxy services will be unavailable for some hours while software is updated on the servers that provide those services.
During the Tuesday, 18 February maintenance window, maintenance work will affect certain services, starting at 5:30 PM and being completed before midnight. The following work is planned:
VPN service: software on the router which provides VPN services will be updated. All existing connections to the VPN will be dropped and an outage of ten minutes is expected.
Wi-Fi and VPN authentication: the software that authenticates all requests for connection to Wi-Fi and VPN services will be updated. No noticeable outage is expected, though unforeseen problems could result in a longer outage.
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.
