DNS Failover is a technology mechanism that automatically updates DNS records if something goes wrong with a DNS name server on the network. When a failure is detected, DNS Failover will be activated to execute different actions to keep your availability. Depending on how you set it up it can only notify the problem, or to solve the issue by giving users a different IP address from an alternative server.
With DNS Failover you can also migrate traffic between redundant network connections.
DNS Failover service is configured on A and AAAA records which point to IP addresses. ClouDNS monitoring nodes check your primary IP address every minute. You can set up the monitoring servers to check if your IP is responding correctly to PING, HTTP(S), DNS, TCP, or UDP requests.
As soon as your primary IP fails to respond, your DNS is instantly updated on all ClouDNS nameservers globally to point to a working backup IP address or just to disable the failed IP address during the downtime.
You will receive an e-mail notification for every change of the DNS records.
Our DNS failover system monitors your servers every single minute and will keep you updated on the status of your services.
No downtime = better performance (purchases, revenue, ROI, etc.)
Get your DNS Failover up and running quickly in just a few minutes. Just click on the DNS Failover icon for the A or AAAA record you want to monitor and fill the details about the service you want to track. Once your settings are saved, the first monitoring check will be executed within 60 seconds!
