During the Tuesday, February 3rd maintenance window, maintenance work affecting a number of services will occur, starting at 5:30 PM and being completed before midnight. The following will occur:
- Webmail: the webmail software will receive a major update. The webmail site will be unavailable for between one to four hours. The new site has a completely new look. A preview of the new login page is available. Note that it will still be at https://webmail.ru.ac.za/, and use security authenticated by DigiCert. Do not log in to any site which claims to be Rhodes Webmail but doesn't match those criteria.
- DHCP service: the software which allocates IP addresses to devices on the campus network will be updated. No noticeable outage is expected, but in the event of unforeseen problems, devices which are rebooted or connected to the network while the problem exists may be unable to all network services until the problem is resolved.
