Strange DNS issues

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.

$ttl 38400
@   IN  SOA ns1.squirtyvision.com. root.ns1.squirtyvision.com. (
            1240622180
            10800
            3600
            604800
            38400 )
watercenter.org.    IN  NS  ns1.squirtyvision.com.
watercenter.org.    IN  A   67.23.5.122
www.watercenter.org.    IN  A   67.23.5.122
ftp.watercenter.org.    IN  A   67.23.5.122
m.watercenter.org.  IN  A   67.23.5.122
localhost.watercenter.org.  IN  A   127.0.0.1
webmail.watercenter.org.    IN  A   67.23.5.122
admin.watercenter.org.  IN  A   67.23.5.122
mail.watercenter.org.   IN  A   67.23.5.122
watercenter.org.    IN  MX  5 mail.watercenter.org.
watercenter.org.    IN  TXT "v=spf1 a mx a:watercenter.org ip4:67.23.5.122 ?all"
watercenter.org.    IN  NS  ns2.squirtyvision.com.
watercenter.org.    IN  NS  ns3.squirtyvision.com.

Any suggestions?

Hi Jeff,

Hmm... is it possible it was just a temporary network problem?

When I look now, those domains aren't showing any problems using the intodns.com site.

Are you still seeing issues?

Thanks for checking Eric,

I believe it was a temporary corruption of the DNS records. All is working now, but I had to force the update to make it go away.

I added a third IP address, hostname, and nameserver to my server, then modified the records at godaddy to add the third nameserver. After that update, all was fixed.

I wish I could explain it, but there were problems with many of my domains for about a week. Mostly on comcast connections, but some on qwest as well. I use openDNS on my router with a qwest connection and did not experience any trouble, but my friends in Seattle had numerous problems on both qwest and comcast.
