So you want to build your own data center

Why would you call colocation "building your own data center"? You could call it "colocation" or "renting space in a data center". What are you building? You're racking. Can you say what you mean?

It seems a bit disingenuous but it’s common practice. Even the hyperscalers, who do have their own datacenters, include their colocation servers in the term “datacenter.” Good luck finding the actual, physical location of a server in GCP europe-west2-a (“London”). Maybe it’s in a real Google datacenter in London! Or it could be in an Equinix datacenter in Slough, one room away from AWS eu-west-1.

Cloudflare has also historically used “datacenter” to refer to their rack deployments.

All that said, for the purpose of the blog post, “building your own datacenter” is misleading.

Indeed, I've seen "data center" maps, and was surprised they were just a tenant in some other guys data center.
