This is because of DNS resolution, and to test my theory

And add the host in there you are ssh'ing from and this will get rid of it.
That worked, thanks a lot. What is your theory, specifically? My workstation wasn't in the old server's hosts file, and I didn't have the delay. DNS setup is exactly the same on both machines - our firewall first, then two of the ISP's DNS servers.
Perhaps the server has updated to a newer version that does a double lookup on the connecting machine, while the old version only looked up the IP, and the additional forward lookup is not responding at all / as quickly as it should? --Danny
