No, the second server did not find the answer. Instead, it gave you a
referral - note the lack of an "ra" flag in the header. The second
server is not willing to do recursion for you, and therefore did not
try to resolve the final answer to your request, whereas the first
server did, failed due to lame delegations, and returned a failure
message.
