I have found that, with only one unnamed exception, if you write to firstname.lastname@example.org
it will get forwarded to the appropriate people. Some places it takes a
while, while others (I must plug ANS here.. they are very well organized
with regards to email delegations) are very quick. Writing directly to
anyone with regards to network issues is not a good thing. Some NSPs have
a specific person that only handles peering contracts.
