Contract negotiations advice?

[patrick at zill.net (Patrick Giagnocavo)]

I am dealing with a large telecom which purchased the small telecom I
signed a contract with.

Despite signing only 1 contract with them, the two racks, and the
bandwidth which feeds 1 rack (I connect privately to the second rack at
no charge) all have different termination dates.

How signing one contract resulted in 3 different end of term dates,
months apart, I can't quite figure out.

Can anyone point me to a mailing list or discussion forum containing
advice on dealing with such issues?  And the wider issue of negotiating
good rates with telecoms?

Cordially
