Can you show the netroute you are taking. I usually run into an issue
where it was a cross point 3-4 hops up that was the problem and its
only found after a week or so of handwavy 'things got slower..' , 'not
for me', 'me too', 'hey I am slow now too.' And then it turns out that
some router at Comcast is saying it is a quicker route and you are
going through some backwater network when it should have stayed on
some other one.

Also it would be good to see how the data was generated for the
graphics (and how it is collected) so that other sites can generate
similar stuff to show whats up.
