What is DNS Failover?

DNS Failover service from ClouDNS keeps your sites and web services online in the event of a system or network outages. It makes the life of DNS administrators easier!

DNS Failover is a technology mechanism that automatically updates DNS records if something goes wrong with your hosting servers or 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.

How does DNS Failover service work?

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.

Benefits & Features

Monitoring

Our DNS failover system can monitor your servers every single minute and will keep you updated on the status of your services or take an action if a failover event occurs.

Security

ClouDNS is designed to operate as cloud-based infrastructure service. Our self-developed system for synchronization and data distribution allows our customers to monitor in real time the DNS zones status at each location. Our infrastructure synchronizes your settings simultaneously across all POPs (points of presence), so no additional action is required from your side, once you set up your zones.

Boosts Your Performance

No downtime = better performance (purchases, revenue, ROI, etc.)

Easy Setup

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!

Cloud-based monitoring infrastructure

Our DNS Failover service is designed to run in the cloud, so you never need to worry about outages. We are making independent network and service checks from multiple locations around the world. Each tree checks are unique for maximum accuracy.

24/7 Support

No matter what day, no matter when, we provide continuous, uninterrupted network monitoring and support. Our Technical Support team is online for you 24/7 by live chat and tickets. We can migrate your zones for free, read more here.
