Not as true for HE's tunnelbroker.net, now that they have tunnel servers all over the world, so long as you bother to use a topologically nearby endpoint. Just a few years ago all tunnelbroker.net IPv6 tunnels terminated in Silicon Valley, but now there are better choices for most of us. The list isn't quite public, but it's not much of a secret. You have to create a tunnelbroker.net account (at no cost) and sign into it, then attempt to create a tunnel to get the list: http://tunnelbroker.net/new_tunnel.php There are currently 11 in North America, 10 in Europe, and 3 in Asia to choose from.
