Between 16:00 and 17:00 on Monday, the Rhodes web server will be unavailable for around 20 minutes. The websites listed below will not be available. Since web browsers use the web server to find the proxy servers -- so if you start your web browser while the web server is down, it probably won't be able to get to the web. (Browsers which are already running won't be affected.)
The reason for the downtime is that the lizard.ru.ac.za web server will be moving from 146.231.128.5 to a different IP address. In the unlikely event that you have any software that is configured to connect directly to a service on 146.231.128.5, it will need to be reconfigured to use the correct DNS name of the service.
