DNS server failure
When running an AlertSite Web Test, I am intermittently getting the Alertsite status of
51 - Unable to resolve IP address
Our DNS servers failed to resolve your domain name to an IP address
I want to know where these DNS servers are located? It seems to be about half pass and half fail. I am wondering if one of the DNS servers are down? Is this information available somewhere?
Solved! Go to Solution.
Each location has a primary server that acts as the primary DNS server for all other servers in that location. The primary server at each location acts as a recursive DNS server doing look-ups directly to the root servers on the internet. The records are caches according to the TTL. Hope that helps
