This seems unlikely to me, at least in the US.

Even your cheapest of colo's offer locked cage areas. For someone on Cloudflare's scale, the cost is trivial.

I've been inside some really "low rent" colo's and even they would provide an escort to unlock your cabinet.

Obviously standards/expectations will vary from DC to DC. I'd wager the situation might be different in some of the smaller countries CF operates in around the world though.
