FORMER doesn't mean the environment being queried is necessarily broken. Queries sent to these DNS servers with the +noedns switch get good replies.
The DNS servers being queries are part of a load balancer. (gslb in the name and 30 ms as the TTL) There is also no way of determining the DNS software vendor or version. (well, there are ways to zero in on them...) The FORMERR can be resolved on your end by including SERVER statements in your named.conf. Better yet, contact the owner of the servers in question and let them know you are having issues. They may have something they can implement on their end that will resolve the issue. They might even reveal their architecture and software vendor/version. HTH, Bob
