Our Dynamic SPF operates on a separate architecture to the OnDMARC application across multiple data centres to provide failover to our customers in the rare event of any downtime. 

In the highly unlikely event of Dynamic SPF experiencing temporary downtime across all data centres your emails would still continue to be validated. This is because DKIM would continue to authorise your emails and pass DMARC validation, thereby providing a failover in this rare circumstance so your emails remain unimpacted.
