What is DNS Failover?

来自ClouDNS的免费DNS故障转移服务,可在发生系统或网络中断时使您的站点和Web服务保持联机状态。

With DNS Failover you can also migrate traffic between redundant network connections.


How does DNS Failover 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.
