Round robin works fine if they are all up. Otherwise one goes down, you cache the name, and you keep trying to reach the downed server until it comes up or the name times out of the cache. Of course if you have 4 servers being round robin-ed then this only affects 25% of all queries :) Barry
Why even use a different name? Round robin works fine, and if all the registries participate in a cross-mirroring program, then all would be well, no? If you mirror correctly, it doesn't much matter _which_ host you hit.

You're right, of course. This seems like a fairly fundamental bit o'breakage to have lasted this long. This is the apps fault, of course, unless I vastly misunderstand DNS... but that is a topic for another list. Cheers, -- jra -- Jay R.
