What's the highest speed of the Internet? The speed of light?

I'm not talking about connections speeds exactly, but how fast can a packet of information travel from point A to point B.

Yes, the fastest possible speed for any communication, including the internet, is the speed of light. Most internet links are slower than that. Even light will travel at somewhat less than *c* (the speed of light in a vacuum) if it's moving through a medium, like optical fiber.

This means there's a minimum latency, that is, the time required to go from point A to point B, depending on distance between the two points (about 1 millisecond each way for each 300 km). If you're connected to a server 3000 km away it's going to take at least 20 milliseconds to get a response.
