Some sound advice.
To test a website, you do not need to put in the port number. The test will default to port 443 (HTTPS). So I was able to test Dreamhost.com by just using “dreamhost.com” in the form. At the time I tested, dreamhost had not updated to the fixed version of OpenSSL, and so the test reported it as vulnerable.
Here is the address of the test tool.
In case you wonder, osomac.com is not affected.
