If DNS Express performs a zone transfer more frequently than every 15 seconds, the new data will not become available until there is a 15 second period with no zone transfers.
Updated data in zone transfers is not available.
DNS Express performs a zone transfer more frequently than every 15 seconds.
There are two workarounds: -- If possible, configure the environment such that there is a 15 second window between zone updates. -- If possible, disable 'notifies' from the master DNS server and lower the refresh time of the SOA record, forcing DNSX to check serial numbers of the zone at the refresh interval and refresh the zone if needed.
DNS Express no longer has the 15 second delay, so updated data in zone transfers is immediately available.
