Re: Round Robin DNS

["Christopher A. Woodfield" <rekoil () semihuman com>]

One solution I've seen implemented is to put one nameserver in each data center, 
and that nameserver only responds to queries with IPs that are in that location, 
and sets a short TTL. So, if that center loses connectivity, no new DNS queries are 
being answered with IPs in the affected location. The only "lag time" is the DNS 
TTL.
