FYI: adobe.com GSLB DNS servers choking on "nsid"

[Phil Mayers]

Just to save anyone else the trouble, I've just found that some of the 
GSLB names for *.adobe.com return NXDOMAIN with "nsid" options present:

# dig +norec +dnssec +nsid @193.104.215.247 ardownload.wip4.adobe.com
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 50062

# dig +norec +dnssec @193.104.215.247 ardownload.wip4.adobe.com
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 20650

;; ANSWER SECTION: <etc. etc.>
