During the course of today the bulk of our network monitoring system, Big Brother, was relocated to a new machine. This migration is not yet complete and, as a result, the information displayed by http://bb.ru.ac.za/ may not be entirely accurate. In particular, several systems are shown as having no report (purple). It is likely that this is a result of the change rather than a real fault on the system concerned.
The migration of the monitoring system will continue tomorrow.
