Keep in mind that you are talking about a very rare event -- total
loss of a data center or connectivity to it. Even if you have to
manually reroute a subnet to fail over to the redundant site, and that
takes say 30 minutes to settle...a 30 minute outage for a once in ten
years event is not really an issue.

Miha,
Phones try the second DNS server automatically, so DNS refresh is not
usually a problem. The problem is with some PBXs that don't support
RFC3263. In this case, the client can implement automatic failover via
scripting, but you don't have control over it.

Hi Flavio,
thanks for your replay.
What would you suggest? we are ISP, subnet migration should
not be a problem but this will resolve down time as this
would need time to network admin re-route subnet.
What about DNS srv. This would not be a problem with zones
as need time to refresh (i just did I quick look to RFC
that you posted in previous post.).
tnx!
