I’d recommend you approach it from a hyperlocal perspective, find the local data center you think will be best for you then look up who is offering colo out of that data center. Then do some network testing. Maybe compare a couple data centers. The providers are going to vary in most cases. So I don’t recommend looking for a specific provider just because it works for me or someone else. You’ll get to pick your bandwidth provider too in many cases.

I like to make sure the network hop path to my home is as direct as possible. My ISP has a large presence in one of the local “backbone” data centers so that’s where I find the best results. But still do testing, it’s not all about location when it comes to latency. If you visit the data centers, or online, they often list names of colo providers. They’re often rather small shops and not large brands so going to be very location specific
