I don't know anything about your specific case... but with an 100% optimum
light-path you're looking at ~55 ms RTT between ANC-NYC (1ms RTT per 100km
of fiber):

Of course fiber very seldom goes direct path, so 124ms sounds plausable and
could most likely be improved by a little bit by choosing another provider,
but would that really substantially improve your interactivity problem?

I'd be looking at WAN optimisers like Riverbed, Juniper, Silverpeak etc.

Even if you move providers and it works better today there's no saying they
won't move their paths about and you'll be back on the same boat tomorrow.
