I am looking to setup a really simple manual
(potentially-involving-human-beings) failover for a website served by
webservers at geographically and BGP A/S seperate locations. I've =
the failover mechanism will be a change of IP for the www A record, so I =
a really low TTL on that A record.
I figured that a TTL of '0' might be misinterpreted by caches and =
that 60s would probably be about right but I simply don't have the =
to make a sound judgement myself.. So my question is: What would be the
lowest 'safe' TTL that I could give the A record?
