"www.mozilla.com" is not a domain, thus it has no source of authority
record.  "mozilla.com" is a domain, and so is "geo.mozilla.com".

Notice in the earlier query, it looked up www.mozilla.com to be a
CNAME to www-mozilla-com.geo.mozilla.com before stripping the hostname
portion off, and searching for the SOA for geo.mozilla.com.

All the same:

[daniel at loki ~]$ nslookup
> set type=SOA
> geo.mozilla.com
Server:         129.173.1.10
...
Authoritative answers can be found from:
geo.mozilla.com nameserver = ns0.geo.mozilla.com.
geo.mozilla.com nameserver = ns1.geo.mozilla.com.

[daniel at loki ~]$ nslookup
> server ns0.geo.mozilla.com
Default server: ns0.geo.mozilla.com
Address: 63.245.208.22#53
> www-mozilla-com.geo.mozilla.com
;; connection timed out; no servers could be reached

Definitely something wrong with those mozilla DNS server, but somehow
eastlink has got a work-around.

-D.
