Yes, if we hypothetically built a completely new optimized global fiber network designed for gaming with direct connections between all continents without unnecessary detours and bottlenecks, then 80 ms could be close to the highest ping (round trip time, RTT) between the most distant continents, such as Europe ↔ Oceania.

Here's why:
1. Distance limitation:
The longest cable run needed is between continents like Europe and Oceania (~16,000 km).
• Light in a fiber optic cable travels at about 200,000 km/s, which gives a ping of:

2. Direct connections:
If we build cables directly between continents without routing traffic through multiple intermediate hubs (which is often done via Europe or the US today), we can minimize latency.
3. Modern technology:
With new optical cables and minimal equipment in each node, we can keep the delay from processing and routing to a minimum.

How this affects the continents:

Assuming this optimal network:
• Europe ↔ North America: ~30 ms.
• Europe ↔ South America: ~45 ms.
• North America ↔ Oceania: ~65 ms.
• Africa ↔ Asia: ~35 ms.
• Europe ↔ Oceania: ~80 ms (the highest value).

This means that the highest possible ping in the world would be around 80 ms, even between the most distant points.

Comparison with today's internet:

Today we have a much more fragmented network, and ping can be significantly higher depending on traffic and routing. With a new, gaming-optimized network, this dream world of a maximum of 80 ms would be possible, even between all continents.
