I am helping a carrier on a new fiber build. Trying to determine where to collocate in this building. There is no central meet-me room, but instead there are three 'gangs' - landlord and two major colo providers. 
Any insight on the best provider in this facility would be appreciated. We want to minimize cross connect charges and delays and avoid being taken hostage.
