DNSViz: A DNS visualization tool

DNSViz is a tool for visualizing the status of a DNS zone. It was designed as a resource for understanding and troubleshooting deployment of the DNS Security Extensions (DNSSEC). It provides a visual analysis of the DNSSEC authentication chain for a domain name and its resolution path in the DNS namespace, and it lists configuration errors detected by the tool. Your feedback is appreciated.

NOTE [2017-01-20]: An attempt to update the operating system on DNSViz servers led to an extended outage. The DNSViz database, which stores historical analysis results, is currently in a state where it cannot boot up. As a workaround, the DNSViz website has been modified to function without the use of the backend database. This unfortunately means that historical results are unavailable until we can recover the database system.

NOTE [2017-01-23]: The database system has been restored and historical results are again available.
