dig: couldn't get address for 'ns.peerlesswebhosting.com': not found

Try making sure that you have A records for ns and ns2. Or better yet,
have someone with the proper infrastructure host your DNS (transfer
your domains to namecheap and they will do it for free.) Some large
ISP recursors are intentionally broken for "resource conservation" and
will simply return failure when not all of the nameservers can be
contacted or ignore TTL values so that they can cache you for longer.

Earlier, when I tried ns.peerlesswebhosting.com it worked, and only
ns2 was missing. Now both are missing. I'd imagine you've been messing
with it since you've sent the email to list.

Also, it might be nice if your SOAs matched your glue records.

I can't see anything else obviously wrong, but that is at least a
starting point.

HTH,

Bill.
