I use FIOS. Here is my result:

10. iad23s05-in-f6.1e100.net 0.6% 164 343.2 712.9 35.1 24215 1890.
In my case, I suspected two things.
1. congestion (verizon over subscribed)
2. packet out of order (high packet drops in alternet-google could be
a symptom of multipath)
Not sure which has bigger performance impact to youtube.
