FYI
66.62.140.38
from here in So. CA.

average 80-100. But often increases to 200-400mSec then timeouts, for tens of seconds for minutes. I just watched it go from 90 to 500, then timeouts, then back to 80mSec in two episodes.

Not my connection: pings to yahoo.com are without anomalies (steady 50-60mSec)
