If they're using some CGI or other utility to update DNS (rather than
updating db files directly), they could be hosing your serial number
periodically due to a bug. Just an idea. This would explain "scratching"
your zones. Alternately, maybe they're running a slave to another ISP's
master with a two-week refresh. Disclosure: I didn't look at the output you
sent but simply went with blind theory.
