The 768/128 service is not guaranteed bandwidth. It is the maximum that you
will receive. During off peak periods you will see your download speed
increase up to the point where you can see it hit a wall. On our GTE home
connection that is about 1 meg/minute. What the telco does is add additional
ADSL cards to a rack at the local switching office.
Each rack is served by its own line to a larger POP. I believe (if I recall
the conversation with the installer) that each rack holds 16 circuits. As
the rack fills, your available bandwidth will tend to drop.

That said, we have been very happy with our GTE service ("Bronze Plus")
which is about the same price as the additional 56k phone line we canceled.
At its worst is quite fast. Even uploads are quick since we do a lot of FTP
our web and database servers from this location.

DSL is similar but the bandwidth dilution is limited by Telco practices.
This is typically superior to cable companies who will happily put 2000
people on a network served by a single frame relay t-1, 12 tiers below a
backbone.

The real problem with ADSL for servers is the "A" part. The 128k upstream
rate is what users see when attempting to talk to a server on a DSL line.
This would not seem adequate for any online system beyond initial testing. A
co-location is probably the best bet for almost any game provider. Our
(PulsePoll.com, not game) servers sit on a 100mhz Ethernet connected to huge
network with over 500mhz of bandwidth. We pay $500 per month for this level
of service and have awesome performance. While this is excessive for a
noncommercial enterprise, smaller IPs will co-lo your server for far less.
