Equinix is a carrier neutral facility, going directly to them would require a large commit of colo space, bandwidth, and you have to buy your own network equipments. Do you know any good provider that resell colo space and bandwidth in those Equinix facilities?
Last time I talked with an Australian colo hosts (about 9 months ago) they gave me a price-tag of $50-60k/month for a dedicated 100mbit line. And told me to go talk directly to Telstra (main bandwidth provider in australia). Bandwidth prices here in aussie are ridiculous because there is no land-line from Australia to the rest of the world.
