Certificate warning from OpenDNS when accessing a secure site

Normally, when a domain is invalid or failing while using OpenDNS, you will see the OpenDNS Guide page (http://guide.opendns.com/). Sometimes, the domain that is invalid/failing is an HTTPS (secure) site. In this case, the domain name (guide.opendns.com) doesn't match the failing domain (www.opendns.com), which triggers the SSL certificate warning.

OpenDNS is not pretending to be the original site. It's simply that something in the original site is misconfigured to point to an invalid domain, perhaps in a graphic or JavaScript file. In any event, the domain fails, and OpenDNS Guide is trying to respond.

The two graphics below are an example only (made up domain). Your browser certificate warning may look different.

Here is what it looks like if you Show Certificate.
