While the urgency of low latency in the financial world peaked some years ago, it's still a significant force and not just between New York and either Chicago or London. Today Japan's NTT Communications took aim at a different route, that between the financial exchanges of Japan and Singapore.
NTT has launched new ultra-low latency connectivity between JPX's AP3 data center and SGX's data center, bringing them within 63.5 milliseconds of round-trip latency. That's only two hundred microseconds faster than what they had been offering since April of last year via the new Asia Submarine Cable Express (ASE) deployment, but it's enough to make a difference in the trading world. NTT cut that much off by adding a PoP within the AP3 data center in a better location that then takes the shortest route possible to the landing station.
In the US, many don't realize that the distance between Tokyo and Singapore (5321km) is almost as far as the transatlantic path from New York to London (5576km). But there's still room, perhaps, for even lower latency someday, given that Hibernia's new transatlantic crossing manages the latter route with round trip latency of under 60 milliseconds.
