Speed tests....
I chose to participate in the FCC's speed tests of broadband service providers, and I get a monthly 'report card' on the performance.
Allow me to paste in the results for April and May of this year I have a 10/1Mbs tier.

I haven't taken thew time to view the details of the underlying data, but it would be interesting to notice when the service quality does drop off.
