Lower Latency

[Fluffy Frufflebottoms]

This year our game server provider will be adding new datacenters and pop locations in Europe and Asia. Now while our server will still be in DC this does mean that we will have a direct internal fiber line going to these locations. This will cause a huge drop in latency in these parts of the world. For those in Europe you may see pings as low as 40ms!

How did they manage to exceed the speed of electromagnetic propagation in a vacuum over optical fiber? Do they charge extra for breaking the laws of physics?

The primary issue with latency in europe is the number of hops and the equipment used at the exchange. For some areas there will only be 1 hop to their local exchange this will make it so that pings there are basally the same that people playing in Seattle see.

Sounds awesome. Let's game on!

Heh, the distance between Washington, DC and Seattle is a good bit shorter than the distance between Washington, DC and London. In the straightest line possible, the link to London shown on the map would be just around 6,000 kilometers. With c at ~300,000 km/s, (6,000/300,000) = 0.02s = 40ms RTT. The refractive index of an optical fiber at 1550 nm is about 1.5 (if you're feeling optimistic and generous.) (300,000/1.5) = 200,000 km/s. (6,000/200,000) = 0.03s = 60 ms RTT in a generous and optimistic estimation. In the real world, though, all but the most expensive undersea links hover around 75-78 ms RTT, so expecting lower than 90 ms RTT from the server to clients in Europe would likely leave people fairly disappointed.

You forgot to factor in the size of the tubes.

Fluffybaby...I love you...but it's a weekend and you just exceeded your MPP (math per post) allowance. This is a very serious offense. Now I'm going to have trouble watching football today because my brain, which was happy in its resting state, is now defunct.

Actually the new centers are quantumly entangled so to produce no latency...

Sweet go to hear because I live in san Jose and so That's EXTREMELY good news for me.....
