Why are they a few days behind?

Went along to Internet World today and was suprised to find one of the speakers at a lecture I attended, was from a man who works in the Amazon Web Services department (the service that provides Alexa Share with the Alexa.com API). He was basically plugging the new Amazon S3 service, but I went up to him after the lecture had ended and asked him why all of the graphs and data were a couple of days behind on Alexa. He replied, "this is because we receive 300TB of statistical data per day and it takes a long time to process".

...

What?

...

Did I hear him say 300 terabytes of data per day?

Bloody hell!

No wonder why the graphs are a few days behind!

That shut me up for the rest of the day...
