During the Tuesday, 2 March maintenance window, maintenance work affecting a number of services will occur, starting at 5:30 PM and being completed before midnight. The following work is planned:
TERMINALFOUR: the TERMINALFOUR content management system will be updated. We expect an outage of at least two hours during which time it will not be possible to change content managed by TERMINALFOUR, but already published web pages will still be accessible.
Server software updates: software on the servers which provide the following services will be updated, resulting in outages of up to 15 minutes per server.
DNS
DHCP
NTP
RT
Web proxies
Registration system
Incoming e-mail
Outgoing e-mail
IMAP e-mail mailboxes
Webmail
Mailing lists
SMS
Provisioning (web proxy autodiscovery)
Wi-Fi and VPN authentication
CHERTL Evaluation Assistant
Network graphs
Network monitoring
RU Single Sign-On system
Main web server (www.ru.ac.za, etc)
University administration and meal booking systems
SEALS Library consortium services
Network printing services (iPrint/PaperCut)
File servers/home directories (gnu, serval)
While we try to publish a list of all service-affecting work here in advance, the list should not be considered exhaustive and other low impact work may also be undertaken during the maintenance window.
This maintenance work is being undertaken in the ITSC-approved scheduled maintenance window.
Update, 16:28 2 March: the TERMINALFOUR software upgrade has had to be postponed. Normal server software maintenance will result in a 15 minute outage for TERMINALFOUR, though.
