What Hacker News says
7 sourcesI am looking forward to this being supported officially in the mentioned daemons. The authors should also work with Qualys [1a][1b] development site and open source developers [2] that test TLS configurations to add additional tests early on.

1 points · Open discussionIs DNS resolution enabled on the server? If so, do the clients all have reverse DNS? Are all of your DNS servers working? Have you enabled debug logging for a period of time? Is there a common pattern of the source IP's that have the delay? For what it's worth, you will get a bigger audience of windows server engineers on serverfault. [1] You could also point testssh.sh to your server to see if it finds anything odd. [2]
