I have been running a CentOS server and BIND for about a year. Recently I have been having trouble with some domains and DNS records. I ran http://www.intodns.com/squirtyvision.com to check my top level domain and name servers, all is well. Another domain watercenter.org has been running fine for a year, but suddenly stopped working through Comcast and qwest, and is reporting numerous errors at intodns.com i.e. it reports that the DNS servers are not responding, that there is no A record for www, etc.
Everything seems fine in the DNS record, so I cannot figure out what might be causing the trouble.
