I was trying to test this hostname with SSL Server Test:
I got this message:
"Hostname is on our "do not scan" list"
Can you give some clarification on why the hostname is on that list? When was it added?
I cannot comment on any specific case, but I can explain how we handle blacklisting, and why it happens.
Whenever someone complains about our scanning activity (I am talking about SSL Labs and SSL Pulse), we will routinely add them to our blacklist. We don't ask them to explain themselves. Their reasons vary, but it's mostly because they don't like to be scanned. In many cases these complaints are automated. There have also been cases where people don't like their score, and think it would be better to hide for a bit, until they improve. There's often a genuine desire to fix things, but some large organisations need substantial time to figure out how to make it happen. Based on the complaints I have seen, most are of technical nature. For example, an IDS will pick up something in our traffic (for example, recently some IDS complained about us sending too many cipher suites in the handshake), and then the system administrator will request that we do not scan them any more. Further, blacklists are often specified for large IP address ranges (e.g., a system administrator asking us not to send any traffic to them), which means that a blacklist for one site may affect many others (e.g., think hosting companies and shared infrastructure).
