Subject: Short-circuited traceroutes on FIOS

Anyone have an idea why there are some destinations that on residential
verizon fios here in NY area terminate right on first external hop?

There seems to be a CDN common denominator here. On other networks with
more typical BGP paths and traceroutes, users are reporting issues
accessing these sites.
