Derek,
I'd be curious what the results of the following tests are:
http://broadband.mpi-sws.org/transparency/bttest-mlab.php
This one said on http and ssh tests there was no indication my
connection is subject to traffic shaping or throttling. Below that it
said passing the test does not mean there isn't any traffic shaping.
The other two I couldn't get to work. The two below I couldn't use.
Both said they needed something called web100 to work. I couldn't find
a version for a 3.2.0-38 kernel
I'm wondering if there's something else going on. The pauses, timeouts,
or whatever they are last for varying amounts of time. The pause may be
3 seconds or it may be 30.

The second two have public servers you can use a client against.
Start with the first one and do a compare of HTTP vs. SSH transfers.
I'm not sure what your terms of use are not what the ISP is claiming,
but if they say they aren't throttling an you can present evidence,
escalate until you can't. Ask for refunds, etc.

Derek,
I think your best approach will be engage the tech when he's out with
the suspicion of throttling as being the root, and ask them if maybe
they are over-estimating the thresholds. 1MB is still a good
connection but if it's resulting in timeouts, maybe ask them if they
can take the threshold to 3MB for 2 weeks to see if you have a better
experience. Once you get that attention focused on the potential
issue, most network admins (being contacted by the tech) would be
curious on why you experienced it and will start digging a little
more on their own to see if it's some other problem that is causing
the throttle to choke the line.
Your goal should be to engage and encourage them to look into it
while being their "test subject" in an "experiment". People typically
eat up that type of approach since it really appeals to their curious
side, which is what most-likely got them into network administration
to begin with.
Remember, the technician is your gateway to the network admin. He'll
confirm all the physicals for the admin and yourself.
Just my two cents. Very interested in seeing how this challenge works
out.

The more I think about it, the more I think you're right. I did
some usenet harvesting using encrypted connections and had no
problem. If only I could call earthlink and get in touch with
someone in this country. I'm guessing they don't tell their
overseas tech support very much.

This is a classic example of QoS usage.
The VPN connection doesn't experience the problem because the QoS
settings for VPN would have a no throttling policy attached. SSH
would typically be non-throttled as well.

For several weeks I've had a problem with my earthlink dsl
service. Anytime I'm doing something that uses all or most of my
downstream bandwidth, all data coming into or going out of my
apartment stops. At the same time I'm downloading something a
series of updates for kubuntu and listening to streaming audio,
both stop. If I'm using my windows box to download something
else, that too stops. After a pause lasting anywhere from a
second or two to 15 or 20 seconds, the downloads resume. A few
seconds later, there's another pause. This cycle repeats itself
until the download is complete or I give up.
Each computer has two nics. The problem persists no matter which
one either machine is using for it's internet connection. If I
remove the router, connect the dsl modem directly to either
computer, the problem persists. I even went to the closet and got
the modem when I had dsl from AT&T. I set it to work with the
earthlink service and the problem persists.
Saturday an AT&T technician was here, checked the line from the
cord that plugs into the dsl modem and says the line is in
excellent shape and noise levels are very low. This is not
surprising since I live less than 1/4 mile from AT&T's local
office where all their equipment is.
Since I've tried two computers, 4 nics, two dsl modems and removed
the router, and the problem still persists, I'm guessing the
problem is somewhere at earthlink's end.
Tonight at 21:30 EST, an earthlink tech support person from
somewhere in India called to tell me they had fixed the problem.
While he was on the phone I tried downloading something else and
guess what. The problem was not fixed. As near as I can tell,
the dsl connection does not go down. The earthlink people say it
stays up. The lights on the modem that are on when the connection
is up never go off or blink.
The man asks me what dns settings I use. I tell him 8.8.8.8 and
8.8.4.4. He says I should try earthlink's dns servers. To humor
him I changed the settings on the windows box and guess what. The
problem did not go away.
Maybe I'm missing something, but it's my understanding that once
the download has begun, that dns has already done it's job and has
no further role to play. One more thing. If I use a VPN
connection, I have no problem with it.
Any idea what's going on? If you were to venture a guess, would
you say the problem is at my place, with AT&T or with Earthlink?
Thanks
Derek
