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):

<http://gc.kls2.com/cgi-bin/gc?PATH=anc-nyc%0D%0A&RANGE=&PATH-COLOR=red&PATH-UNITS=km&PATH-MINIMUM=&SPEED-GROUND=&SPEED-UNITS=kts&RANGE-STYLE=best&RANGE-COLOR=navy&MAP-STYLE=>

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?
