Carrier-neutral data center in NYC with good connectivity to long-haul and local loop

Dear all, we want to establish a presence in NYC and will need to collect a few local loops (10M-100M) from around NYC. From there, we will connect back to Germany. So, in summary, we will need: * 2-5 rack units to allow for initial deployment and growth * good connectivity to local loops * good connectivity to long-haul back over the Atlantic and within the Continental US While I already compiled a preliminary list of possible choices, I would like input on what DCs would be well-suited for this. As an aside, who are the most painless and efficient Local Loop carriers within NYC and the US? AT&T and Verizon come to mind, but I don't know the local market at all. Thanks, Richard
