<div>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.</div>

<div>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. </div>

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