Technical Details

Service Type: Production

Server Name: ns-core-seb-1.dsc.umich.edu, ns-core-lsa-1, ns-core-fxb-1, ns-core-cool-1

Comments:

Based on the results of the change on 9/15, adjust server Anycast addresses on some of the four core resolvers to determine whether the servers or their network location has an effect on the latency. Results: ns-core-seb-1 cannot get 10.10.5.5 traffic. Swapped cool and fxb instead.
