Since a few weeks ago, every time I would run SSH to sign into my server I would have to wait about a minute before I could even get a key/password prompt. The problem never really went away, so I contacted my ISP.
After a few email exchanges with some SSH debug logs and traceroutes, they added a reverse DNS record to see if it helped. Strangely enough, it did. I've never had a reverse DNS entry associated with my IP, and I've never had any trouble with it in the past. Only recently did connections start to halt because of it.
So, if you don't have a reverse DNS entry on your IP and have been noticing slow SSH connections, call up or email your ISP to get one added. You will love your connection that much more.
