During the scheduled maintenance window on the evening of Tuesday, December 6th, there will be periods when DHCP, DNS and NTP services will be unavailable. These are critical services on the network, so almost all network usage (including access to the Internet and potentially IP telephones) will be adversely affected in the times when those services are unavailable.

This maintenance work is being undertaken in the ITSC-approved scheduled maintenance window. Work will start at 7:00 PM, and it is expected that all work will be completed before midnight.
