Earlier quoted context omitted.
A super duper secure locked cabinet acessible only to them or anyone with a bolt cutter. You want to host servers on your own hardare? Uh yikes. Let's unpack this. As a certified AWS Kubernetes professional time & money waster, I can say with authority that this goes against professional standards (?) and is therefore not a good look. Furthermore, I can confirm that this isn't it chief.
Colocation is when you use your own hardware. That's what the word means. And you're not going to even get close to the cabinet in a data center with a set of bolt cutters. But even if you did, you brought the wrong tool, because they're not padlocked.
Otoh, maybe you've got a cabinet in a DC with very secure locks from europe.... But all are keyed alike. Whoops.
A drill would be easier to bring in (especially if it just looks like a power screwdriver) and probably get in faster though. Drill around the locks/hinges until the door wiggles off.
