Sprint seems to be having capacity issues, I've noticed L3/Sprint SanJose
goes thru some serious degradation during most of the day.. Supposedly the
issue has been open in both NOC's for 2-3 months...they're "working on it"..
Have you tried contacting C&W about it? Sprint wasn't incredibly helpful,
but L3 provided some information for us..
Regards,
Matt

Subject: Sprint / C&W peering issues?
The past few days, I've been noticing packet loss, apparently at the
points where Sprint and C&W exchange traffic. Today, I emailed a note
about this including the output from a few mtr's in each direction to
noc@sprint.net, and though I got no reply, an hour or so later, I noticed
packets were taking a slightly different route (apparently going through a
different peering connection in a different city if you believe the
hostnames) and the packet loss was gone and round trip times much better.
I left the office for a bit, and now that I'm back, I see the packets are
back to using the old peering connection that I can only assume must be
overloaded. Anyone know what the deal is?

Hop 10 is a router with some packet filtering...no response is expected
there.
