We recently tried to upgrade to latest release of external-dns, but this resulted in R53 records taking too long to be created/updated/deleted (20mins + per operation).
We saw in the external-dns logs that the service was continually trying to action UPSERTs on all R53 records managed by external-dns.
Recreate issue in test cluster, attempt to resolve the problem
