Interesting. I began to notice trouble reaching google about a week ago from 2 different east-cost Verizon FiOS lines -- one business and one residential -- but my problem appears to be congestion at the AS701 <> AS15169 border. I'm not noticing any loss across AS701.
These problems began around 9am Eastern on Saturday Feb 19th -- see attached smokeping graph. You can see the diurnal pattern in the loss -- packet loss peaks between 9a-4p ET. Of course, I can get toipv6.google.com without any loss at all via my HE tunnel!
In both cases, mtr shows ~50% loss beginning at google-gw.customer.alter.net (184.108.40.206), the first hop in AS15169. It's clear that I must be losing more ICMP than TCP packets given that google webpages come up fairly quickly, but youtube videos hang ever since this started.
Anybody else seeing this?
