We got reports that worldnic DNS servers were not responding and in our preliminary search we found that all the ns?.worldnic.com DNS servers were indeed not responding to requests.

For a while we had trouble reaching the network solutions website (redirection loop), next their website spoke of "a widespread outage" without more detailed information. Now it says "At 10:45 a.m. this morning, we experienced a hardware problem that impeded traffic to our hosting and e-mail servers.  We experienced technical difficulties with an auto recovery system.  At 11:50 a.m. the system was restored. " which would seem to indicate the problems are over.
To the more technical reader it might be clear that the problem that was reported had nothing to do with their email nor their web hosting servers, but with their DNS servers. Or perhaps these servers had issues as well, but that hardly matters to the average user when DNS isn't working as it should.

Also remember this diary about a very similar incident.
