dotUS DNS problems on July 7

Sat Jul 23 18:33:45 UTC 2005

On July 7, 2005, NeuStar received a handful of reports that DNS 
resolvers were unable to resolve dotUS domains, plus the mention of 
the problem on the NANOG list.  From the reports received, the DNS 
problem seemed to impact a limited number of independent 
organizations but was not widespread.

The reports followed a maintenance operation at one DNS site.  During 
the maintenance operation a new piece of network equipment was 
installed.  At approximately 10pm EDT (July 8 0200 UTC) the state of 
a previously operating load balancer was reset.  At that time 
affected servers at independent sites resumed resolving dotUS names.

We have reviewed and revised our maintenance procedures to prevent a 
reoccurrence of this issue.
