LACNIC to start allocating from 189/8 and 190/8

My results match Randy's. I looked at these blocks from several 
networks (ATT, Cogent, PSI, XO, Comcast). All have the routes 
showing. ICMP Echo packets do not come back via any of them. Either 
the machines aren't listening, the echos are being blocked, or 
there's widespread blockage.

Traces appear to make it to Brazil before dying in all cases, 
pointing at an issue closer to where your test machines are located.
