So as far as my machine's source address is concerned, even if the servers are anycast, there are still only two servers which reside on a single point of failure. Anycasting doesn't help me one whit if there are only two servers for my named to choose and both of the ones visible from my location are down (even though their routes are up) -- this is IMNSHO irresponsible for a gTLD operator. If anycast is the game, there should be much more than just two addresses to choose. Ideally, there should be about six, and certain servers should deliberately *not* advertise certain anycast networks, in an overlap mesh that allows one point to fail while others still respond. For instance: USA server location A advertises networks 1, 3, 5; USA server location B advertises networks 1, 3, 4; Europe server location A advertises networks 3, 4, 6; Asia server location A advertises networks 2, 5, 6; or something to that effect. -- -- Todd Vierling <tv () duh org> <tv () pobox com>
