Re: Data feed request

Hello Luis, 

Ouch, the traceroutes to those sites are really not acceptable, especially
the packet loss.

I have forwarded this to Tom Yoksas, who may have some better approaches
to obtain the data via ADDE.

I am looking into the Caribbean subnet to see where the connect nodes are,
and hopefully will be able to find a "nicer" route...

More later,

-Jeff
