Hi I would like to change Wildcard IPv4 and IPv6 when down using your services DNS Failover.

Example:

When UP set:
*.mydomain.com ---> A -------> 162.163.164.1
*.mydomain.com ---> AAAA -> 2604:4567:0:456::4

When down change to the second backup server (that have same webpage domain name configured etc, need only change IPs)

When Down set:
*.mydomain.com ---> A -------> 200.201.202.203
*.mydomain.com ---> AAAA -> 2804:4123:0:321::1

Is possible to change IPs for Wildcard DNS when down?

At this time I use Amazon route 53 with this plan: 30 seconds check, if down 3 times check (like 1min and 30s), change for backup DNS records.

I see that your service use 5 min check and only disable or enable records DNS after 2 checks time (like 10 minutes, first time receive a warning and second time receive a down). It's possible to reduce this time?
