[dns-operations] WorldNIC nameserver issues

[David Ulevitch]

We're seeing a number of issues with WorldNIC nameservers failing  
from multiple points on our network this morning and was wondering if  
anyone was seeing similar problems.

We're seeing issues with:
ns47.worldnic.com (domain: cpurocket.com)
ns48.worldnic.com (domain: cpurocket.com)
ns87.worldnic.com (domain insightcollect.com)
ns88.worldnic.com (domain insightcollect.com)

and many many more...

Anyone else seeing these failures?  WorldNIC does a lot of  
authoritative DNS....
