Keynote's primary business model is measuring the performance and availability of public web sites as seen from a distributed network of synthetic probes. They don't offer any services that "track the load and bandwidth on the Internet". Here's what their public/PR type email alert said on the matter yesterday:
Keynote Internet Performance AlertStarting at approximately 5:30am PDT today, a major Internet performance issue was detected by Keynote systems. By 6:00am, the availability of the Keynote Business 40 Internet Performance Index had dropped from its usual near-100% availability to 81% availability:

These sites dropped to near-zero availability:

... They have tracked the attacker back to person that is at the Akamai Technologies ISP. No other information has been given to us at this time. We do not know if the FBI is working on this issue right now, but we expect them to do so. [DMK: Source, beyond overclockers, unknown, reliability and accuracy unknown.]
That's nonsense David. Keynote measurements can distinguish between availability problems caused by DNS outages versus those caused by connectivity or site outages. They manifestly don't track attackers.
