This is not the answer to the question you asked, but why wouldn't you want your packets to take the best/fastest/shortest path, rather than the one that came up heads this time even if it's much farther/slower than the other? I don't know if you're aware but the difference can be orders of magnitude in some cases. Also if your dns is doing a 50/50 round-robin between addresses on different providers, does this mean that when one T1 goes down half of your web hits will arrive at the server ok while the other half fail (at the browser end) due to network unreachable? -Mitch > We have two T1's one sprint one uu-net.
