I tried asking the following in networking, but it does not seem to fit the topics. Maybe there is a better place to ask?
I have a pretty general question about how networks work on ISP (Internet service provider) level.
For example, you live in London and there are a lot of providers for Internet connection, one of which Vodafone, and the other is O2. Both providers have a 50 Mbit/s plan, but the O2 provider has better connectivity to eastern /Asian websites, while Vodafone has more latency and is very slow on lot of them. This is just an example, not a real case. Even if both providers have a local fiber network, international connectivity will be ways better on some than others.
I was wondering what might cause this?
