I do realize this is largely off-topic (though it's on my net machine that supports vintage computing activities), but I cannot think of a better bunch of people to ask. Please reply off-list. I have a long-lived, well-placed and reliable machine on the net, turing.wps.com, and I'm looking to exchange secondary DNS service with someone outside the U.S. or on the East Coast. My server is in a secure, A/B powered telecomm colo in Seattle Washington, 600+ Mb/s to three ASNs. I have a lot of heavy DNS experience so when I foul up I do a really good job of it. I've got a half-dozen zones, all small, and would set up axfr's for you in exchange for me. This of course does not require me to have access to your machines, and vice-versa, we just set up bind config. Swap for like service, no money involved.
