Whew...
Lotta of those..I once spent about 20 minutes on the phone with a tech discussing the various protocols, since he hadn't heard of some of the RFC's...

Even thought I had a major thunderstorm here last night. Lightning actually hit across the street..was loud as hell when the thunder hit about 2 seconds later....never even blipped my connection.
Nature's Shock & Awe at work.
