About this tool

There is a chain of things that have to happen for any internet connected service, such as a website or email system, to function properly. This tool helps to quickly isolate where any issues might be hiding.

This starts with DNS records, which are what translate your domain name into usable information, such as an IP address.

If your DNS information is modified accidentally, or worse, if it's been hijacked, then all the traffic to your website, email or other internet service, may be going to an unapproved or unknown location.
