Looks to me like the latency from Qwest to Google
(chx-edge-03.inet.qwest.net [67.14.38.5] to 72.14.214.78) is quite
tolerable, but the delay(s) inside Google are a tad bit high. I see much
the same thing from work and from home to 74.125.236.52. As soon as I jump
from my provider's upstream (Qwest at work, Cox at home) to Google, the
times go up sharply along the route to 74.125.236.52.
