When I do an mtr from my home to Wikipedia, the host ae20.3518.ear1.Chicago3.level3.net shows a significant packet loss:

What I suspect is happening is only ICMP packets are being lost, not every packet going through that host, since Wikipedia doesn't seem to have degraded performance. Anyone care to offer other explanations or speculation?
