*What is happening?*
Starting at 6AM Sunday July 19th at 6AM we will apply security updates to
NameO and NameP and reboot them,  We will do these one at a time and verify
that things are working as expected before doing the other one.   We
anticipate each machine being down for less than 5 minutes.

These machines provide DHCP, DNS and LDAP services.   Most services should
be unaffected since we have redundant servers, however, there may be brief
interruptions in the ability to log in to some services.

*How long will it take?*
We expect this work to take about 10 to 15 minutes per server.   There will
be a delay between the two as we verify that all is well.  As mentioned
above, the actual outage of service should be much shorter.

*Why is this work necessary?*
For security and support reasons we need to keep our systems running on
recent well supported operating systems and standards.  In addition, we
have new SSL certificates to put in place and are replacing those at the
same time.

What happens if the work is not successful?

We will back out to snapshots of these machines taken prior to application
of the changes.

For Support of UMS software, services, or systems please contact IT Support
Services at 800.696.4357 or by email: [log in to unmask] <[log in to unmask]>
