DNS Query Check
Verify correctness, availability and immutability of your domain DNS records.
What does the DNS query check do?
It verifies the correct operation and content of domain DNS records, watching whether they are available, correct and unchanged. DNS is key for routing websites, email and other services.
Why monitor DNS?
DNS records are the backbone of online infrastructure. If wrong or unavailable, services can fail or be compromised. Early alerts keep your site and email working and secure.
