Earlier today, around 6pm, the DHCP service ceased functioning, causing systems that obtain their IP addressing dynamically to be unable obtain an IP address to use when connecting to the network.
Most systems that use DHCP to obtain their IP address will be affected by this and will not be able to connect to the network after reboot or lengthy disconnection from the network.
Systems that use DHCP but have already obtained an address may be able to stay on the network during this service malfunction – this depends on how individual systems are configured. Systems that do not rely upon DHCP (statically configured hostnames/addresses) should be unaffected by this problem.
Staff are looking into the cause of this problem.
