to deploy PowerDNS in a slave configuration that has multiple
(BIND) masters. In a test rig I'm finding that if I have dual
masters configured on a PDNS slave, and one of the two masters is
unavailable, the slave is querying the absent master and not
failing over to the other. <br>

And even if it receives and accepts a NOTIFY from the functional
master, it still sends the SOA query to the non-functional
master.</blockquote>
<p>The first question is: what version of PDNS Authoritative are you
using?</p>
<p>The second is just to confirm how you have configured each zone
with multiple masters in SQL: is it a single row with a
comma-separated list of masters?</p>
