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.
