Sigh.. the point is that we have 9 (or so) root servers right now. All of those can be counted on to provide name service for anybody for anything, assuming of course that the network is okay. When someone starts blocking certain sites' access, then we basically have 8 servers. Sooner or later, someone else will decide to start blocking. Then we'll have 7. And so on, until everyone has to use different root servers. If you claim to be a root server with data for everyone, you should damn well provide that data to everyone. Otherwise, you have no right to pose as one of the root servers. shag Judd Bourgeois PGP key ID 0xEDC21CA1 [email protected] 25DDE4AF C5AFEF51 6905DC77 360F0387 To all my friends - It's not the end The earth has not swallowed me yet - 311, "Freak Out" - - - - - - - - - - - - - - - - -
