New DNS Nameserver: themis.eecs

by

System administrators in EECS may be familiar with our DNS nameservers cronus and rhea. We now have a new nameserver, physically located in Cory Hall, named themis. If your systems are typical DHCP clients, or you don’t use the EECS wired network, then you should have nothing to change.

We are planning to replace and retire rhea according to the following schedule:

  • Thu Oct 15 — We will update our DHCP configuration, telling Cory Hall DHCP clients to use themis and cronus, and telling other DHCP clients to use cronus and themis.
  • November/December — We will monitor any continued usage of rhea for DNS, and periodically alert system administrators so they can update their systems to use themis instead.
  • early January — We will retire rhea, but will point its name and IP address at cronus.

We will update this post when the work is complete, or if there is an unforeseen impact to the production networks.
