You can get close. There was a guy named Kevin Mitnick who was traced to the general area where he lived using cell trackers. It was an apartment and the investigators then used cell phone tracer to narrow where he was on what floor.

He should be hired to locate the server and also to hack into it.
The ISP you are using has your history. The phone too. Don’t forget about the NSA.
Tracing cell phones is a whole other kettle of fish than tracing IP addresses.
One hop across the country or globe to a server with fraudulently filled out paperwork will effectively hide the physical location of the server. There is nothing intrinsic to an http packet that discloses its physical location. All the various IP ‘location’ tools rely on the assumption that you are physically close to the last IP that has properly filled out information on file. Now you can use latency and other forensics to narrow it down, but it’s still largely guesswork. And as mentioned above, internet IP addys and cell phones are two completely different animals.
Cell phone tracking is different than finding the location of an IP address. The cell phone sends out a regular signal, to check in with the towers nearby. Even if you don’t have access to the towers, there are portable devices that can intercept that signal and then you can triangulate the location if you have enough of those devices.
