During the Tuesday, October 7th 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:
- Wi-Fi controllers: software on the controllers managing Wi-Fi access points on campus will be updated. Wi-Fi access across campus will be unavailable for approximately ten minutes.
- University administration servers: software on protea and canna will be updated. It is expected that all services provided by those servers will be unavailable for a number of hours.
- SEALS servers: software on SEALS library consortium servers will be updated. It is expected that all SEALS services hosted at Rhodes will be unavailable for a number of hours.
- DNS/DHCP/NTP servers: software on the two servers which provide the DNS resolution, DHCP and NTP services will be updated. You may notice that network applications respond slower than usual during those times when the DNS server which is your PC's primary DNS resolver is unavailable. DNS queries will be answered by the secondary DNS resolver, but only once the request to your PC's primary DNS resolver has timed-out.
- Mailing lists: software on the mailing list server will be updated. Mailing list archives will be unavailable for a period of around an hour. Any messages sent to mailing lists during that time will be delivered once the mailing list server is operational again.
- Server software updates: software on the servers which provide the following services will be updated, resulting in outages of approximately five minutes per server:
- RT
- Web proxies
- Registration system
- Incoming e-mail
- Outgoing e-mail
- E-mail mailboxes
- SMS
- Apple Software Update Server
- Provisioning (web proxy autodiscovery, telephone provisioning)
- Wi-Fi and VPN authentication
- CHERTL Evaluation Assistant
- Network graphs
- Guest network access
- Network monitoring
- Firewalls: software on the firewalls which connect the Internet to the campus, SEALS and public networks will be updated. As the firewalls operate as a redundant pair, no noticeable outages are expected during this maintenance.
This maintenance work is being undertaken in the ITSC-approved scheduled maintenance window.
