To be quite honest I've never seen a colo that didn't offer access at all. The cheapest locations may require a prearranged escort because they don't have any way to restrict access on the floors, but by the time you get to 1/4 rack scale you should expect 24/7 access as standard.

Same. We would colo and had racks behind chain link fencing that was locked behind cipher locks
