VUMC IT to conduct legacy DNS shutdown

Posted by on Monday, September 12, 2016 in Outage.

DNS users,


Beginning on Sept. 15, VUMC IT will begin shutting down legacy DNS servers in order to shift all users to new DNS servers.  Due to the number of users still operating on old servers, the inability to determine which users are working on those servers and the possibility that critical systems could be impacted by a complete stoppage, VUMC IT will be conducting a series of service stoppages.

By initiating temporary service disruptions, individual owners can identify systems that have not been moved to the new DNS infrastructure and VUMC IT can make the necessary modifications. These temporary service interruptions will be conducted in stages, and only for short periods of time.

The schedule for these temporary shutdowns follows:

  • 180 minutes: Thursday, Sept. 22, 9:00 a.m. – 12 p.m.

  • 360 minutes: Tuesday, Sept. 27, 9:00 a.m. – 3:00 p.m.

Medical Center devices currently configured to resolve against:

  • 129.6.22
  • 129.233.40
  • 129.48.90

Will need to be reconfigured to resolve against:

  • 108.51.18
  • 150.51.18

NOTE:  This change will only impact systems that have not moved to the new DNS servers.
