ssh delays and drops

[Antonio Rodriguez <arodriguez31@cfl.rr.com>]

I have been noticing lately some significant delays in my ssh
connections when I log in from work. At first I thought that it could
be that my signals were been studied behind the firewall at my work,
but later I found out that some other users had the same problem when
connecting from their homes via putty. I also use putty for win-m$
from work. Some times the connection is even dropped because of the
delay. I have thought of another possibility, which is the port 22
being partially blocked may be by my isp. I don't know how to check
for this. Any ideas?
