This change was completed without incident at 5:30am this morning. We continue to monitor key services for any reliance on this retired DNS system.
At 5:30 AM on Monday, October 25th, our legacy DNS servers will be turned off (houdini.ups.edu 184.108.40.206; babel.ups.edu 220.127.116.11). These servers have been effectively retired for about six months. Any computers with these DNS servers set within the university network should immediately be changed to 18.104.22.168 & 22.214.171.124.
DHCP has been handing out these new DNS IPs for months, and only users who set the entries statically will be affected – should be very few users; we’ve watched the logs to make sure no large population was using the old service.
