I'd bet F-Droid probably is colocated. Nothing in their statement precludes this.

But the assertion by commenters above that home-hosting is a viable or even a better option for a project like this is silly. Colocating a single server is cheaper than a single a Comcast Business internet connection. Air conditioners fail. Electrical failures happen. These things might not be a problem for a personal project, but they're easily and cheaply mitigable risks at commercial scale.
