Also check the date and serial on your root zone.  The zone is
regenerated every hour, and sent out if there are any changes.  I am
currently holding serial 2012092601.

I am curious what you are referring to when you say you have a T1
opennic server?  The T1 servers do not resolve queries, they only
transfer zone files.  If you are actually get dns queries answered by
one of the T1 servers, it is only because they are misconfigured.

One other item of note... I have been noticing outages between Level3
and other providers periodically this week.  In fact, there's one
occurring right now, so my servers are not currently reachable.  In case
you're not familiar with them, Level3 is one of a handful of companies
that provide the backbone trunk lines for all internet communications...
when they go down, everybody is affected.
