Hi Rick;

I don't represent MLab but I do work with them in their deployment of 
NDT.  The system they are using to handle the redirecting of servers is 
called 'DONAR', it tries to find the closest server to test against. 
When you click the link on the MLab page (I think the link is 
http://ndt.iupui.donar.measurement-lab.org:7123/ - this is a real server 
in CA) DONAR will transparently redirect you to the best server.  If the 
server shows up as being in New York on the HTML this is correct, the 
URL may not change in the bar when this happens (so your traceroute to 
the URL will still go to the dummy server in CA).  See attached picture.

Does this address your question?  If you do have evidence that the 
redirect is not working properly I would be happy to put you in contact 
with the MLab support staff to rectify the problem.  Thanks;

-jason
