Error "Host not found"

[Kevin Darcy]

Neither ns.centroindustrialmarysol.com nor ns2.centroindustrialmarysol.com are answering queries for me. Firewall rule, perhaps?

(After typing that domain name twice, it's time to give my fingers a rest now so I don't get Carpal Tunnel Syndrome)

Also, the fact that you are publishing only 1 NS record subjects the resolvability of your domain to a single point of failure (unless of course that one IP address is backed by a cluster of
machines and/or some sort of routing magic).

                                                                                                                                                    - Kevin
