On March 15th at 7pm there will be a software upgrade done on the Queen's DHCP service (automatic IP address assignments).
This will affect all users who use the default ITServices DHCP server (including wireless). During this time a machine will not be able to receive a new address, however clients who already have a network connection should continue to receive service.
The upgrade will take approximately 1 hour and once restored users should notice no change in service.
