In an announcement yesterday, Comcast announced that they will begin rate-limiting their residential high-speed internet (HSI) customers to 250G/month starting on October 1st.  From the announcement:

Comcast said it was setting a monthly data usage threshold of 250 gigabytes per account for all residential high-speed Internet customers, or the equivalent of 50 million e-mails or 124 standard-definition movies.

"If a customer exceeds more than 250 GB and is one of the heaviest data users who consume the most data on our high-speed Internet service, he or she may receive a call from Comcast's Customer Security Assurance (CSA) group to notify them of excessive use," according to the company's updated Frequently Asked Questions on Excessive Use.

Customers who top 250 GB in a month twice in a six-month timeframe could have service terminated for a year.

What a horrible idea, with the implications only to lose customer base.

If that happens, and if my usage results in even a single a notice from Comcast, they can expect to lose one customer immediately.  My wife and I currently have the triple-pack of all three services (HSI, TV, and phone) pulled into our house, and we couldn't have been happier with the results so far.  But our businesses cannot be hamstrung by arbitrary rate limit policies handed down by Comcast.  The idea that service will be terminated at a second incidence effectively puts a gun to the head of legitimate high-end bandwidth consumers.  That's bad policy.

1-800-COMCAST is the number if you wish to voice your own complaint.  I found the easiest way to get to a human is to simply hit 0 over and over.  The system will complain, but you'll eventually get to a live operator.
