In order to perform server maintenance, there will be several
brief interruptions in York's DNS and DHCP services between
7:30am and 8:30am on Tuesday May 15th.

The DNS servers are used by internet applications to convert host
names to network IP addresses.  DHCP servers are used to assign
IP addresses to specific computers at York.

Users who have correctly configured their computers with the IP
addresses of three DNS servers will likely experience small
delays on all internet connections during the server outage.
Users who have configured their computers with only one DNS
server will likely suffer a complete outage on all internet
connections.

DHCP users (ex: campus computer labs, residence network users,
Laptops@York users), will notice a delay of several minutes
getting an IP address from the DHCP servers during this outage.
Any machines turned on before the outage and assigned IP
addresses by the DHCP servers prior to the outage will not be
affected.

Information about York's DNS and DHCP service is available in
the Network section of the CNS website (http://www.cns.yorku.ca).

Questions or concerns about these outages, should be directed to
the CNS Helpdesk in the Steacie Science Library Building, (voice:
736-5800, email: [log in to unmask]).
