We have recently been asked by Nominet to give advice on the >placement >of the secondary name servers for the .uk domain name. 2 or so thoughts that don't seem to have surfaced yet: - nameservers generally get selected on RTT. This means that the only benefit of 2 servers within a short RTT of each other is redundancy/load balancing. - the US and EU are close together in RTT. EU and Asia are not. Neither is Eastern Europe terribly close to West Europe, for that matter. - Placing servers *on* exchange LANs is an awful idea, because a cracked server there has entirely too much power. Think BGP session stealing. Placing one *next to* an exchange LAN is to my mind a Good Thing. My thoughts.... -- Harald Tveit Alvestrand, alvestrand@cisco.com +47 41 44 29 94 Personal email: Harald@Alvestrand.no
