I think they setup a CNAME record for *.oorexx.org pointing to 208.34.240.200 instead of an A record. The planetdomain.com servers respond to A and ANY queries for www.oorexx.org with an A record as expected, but queries for any other hosts (e.g., xyzzy.oorexx.org) yield the CNAME record as do explicit CNAME queries for www.oorexx.org. Probably what's happening is your cache is ending up with a CNAME record for www.oorexx.org, so future A queries end up trying to instead resolve "208.34.240.200" (because CNAME records take precedence over anything else), which it then doesn't know how to resolve. Ask the oorexx.org team to double check that there's no CNAME records for *.oorexx.org where they meant to configure an A record. They probably either meant "*.oorexx.org CNAME www.oorexx.org" or "*.oorexx.org A 208.34.240.200", but "*.oorexx.org CNAME 208.34.240.200" is going to break for any caches that don't internally handle IP address literals.
