Enable NOTIFY to the zone transfer agents
For best results, use DNS NOTIFY on your primary name servers. This notifies Edge DNS when your zone changes and initiates a zone transfer. Edge DNS accepts DNS NOTIFY by default.
If you would like to use NOTIFY requests, you must configure your primaries to send these requests to the zone transfer agents (ZTAs). See Restrict zone transfers to the zone transfer agents to learn how to subscribe to a list of ZTAs.
If you do not use NOTIFY requests, the ZTAs check with your primary name server at the refresh interval listed in your start of authority (SOA) record.
