Question

How quickly one's records will propagate to Openprovider DNS servers when using the latter as slave nameservers?

Answer

In general, new slave zones copy the data of the master zone file within a minute.

Changes on one's nameserver are copied automatically by Openprovider slave servers when the refresh time of the SOA record expires. Openprovider load balancing nameservers (ns1, ns2, ns3) do not support the NOTIFY command to update a slave record.

In case Openprovider slave does not synchronize correctly with the master nameserver, check master's configuration.
