There's a new AAE-1 cable currently being laid (sunk!) that comes online early 2016 that will help. But right now alot of traffic cuts across the US as it's still the 'best' route for reasons other that latency as others have already mentioned. The new AAE-1 will have 40Tbps connections from Europe to Hong Kong so hopefully the routes will start to migrate in 2016 and give us an Easterly route to APAC that has enough capacity to be stable in that direction -- Martin Hepworth, CISSP Oxford, UK On 2 April 2015 at 15:03, Jared Mauch <jared@puck.nether.net> wrote:

What's the reason, there are some telecoms,isp that have paths eastbound, southbound but in routing table they prefer longer path via US ?
Come on - you do know that it's called "policy" routing for a reason? Costs, reserved bw/s for high-rollers, capacity...
Sure, you can use static routes as well[1].
For those that are interested you can take a look at http://www.submarinecablemap.com/ to get an idea of what path might be feasible. I will say that telecom costs tend to be related to political stability, so when computing shortest path cost often comes into play.
Also, What I'm often reminding people is low-latency isn't always the right solution, because loss is more important. I am less concerned about another 25-100ms if there is little jitter and zero loss.
