DNS Server Check
Checks availability and speed of the DNS servers that translate domain names to IP addresses.
What does the DNS server check do?
It verifies that your domain's DNS servers are reachable and working correctly. It monitors the response and speed of the DNS servers that translate domain names into IP addresses, which is key to fast and reliable availability of your web services.
Why monitor DNS servers?
DNS servers are the backbone of internet infrastructure. If they are misconfigured or unavailable, your domain can become unreachable. Monitoring helps you spot problems before they affect customers and gives you evidence for resolving outages or complaints.
