In order to perform necessary software upgrades, there will be two
brief outages to York's main campus DNS servers on Campus.

The outages will take place as noted below:

Tuesday Sept. 21, 8:00 - 8:15am  draco.ccs.yorku.ca will be
unavailable.

Thursday Sept. 23, 8:00 - 8:15am  ns.nic.yorku.ca will be
unavailable.

The DNS servers are used by internet applications to convert host
names to network IP addresses.

Users who have correctly configured their computers with the
IP addresses of all three DNS servers may 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.

CCS strongly suggests that York Main Campus users configure
their machines to use the following search sequence for the DNS
servers:

   130.63.168.21 (ns.nic.yorku.ca),
   130.63.237.99 (draco.ccs.yorku.ca),
   132.251.1.2 (ns2.admin.crestech.ca).

The DNS configuration for Glendon users should be:

   130.63.152.14 (colossus.ccs.yorku.ca),
   130.63.168.21 (nc.nic.yorku.ca),
   130.63.237.99 (draco.ccs.yorku.ca).

Questions or concerns about these DNS server outages,
should be directed to the CNS Helpdesk in the
Steacie Science Library Building,
