DSL Reports has gotten word that Comcast will soon be offering its Internet subscribers a bandwidth usage meter as early as the first week of January. With the new system users would presumably be able to see how much bandwidth they've used, akin to cellular service providers offering estimates to keep customers from going over their allotted limit. Such a tool for Internet bandwidth would let customers adjust their usage habits accordingly.
Back in October the communications companywithout providing any monitoring tools of its own short of installing special software. Additionally, customers are only given one verbal warning before a one-year service suspension if they go over that limit.
Oddly enough when the cap was first announced, we had gotten a confirmation that Comcast's excessive use FAQ still urges people to use McAfee's security suite, but now notes that "we are in the process of creating a usage meter that will measure consumption for the Comcast account which will be available in the coming months.". This was later recanted by a Comcast spokesperson who said "there are numerous free or fee-based meters that are widely available on the Internet to anyone who wants one."
Comcast spokesperson Charlie Douglas tells us the meter must first undergo an employee trial: "When that testing is complete, we plan to launch the meter to all of our high-speed Internet customers. It will be available for free via a customer's Comcast.net account and it will enable them to very easily keep track of their aggregate data usage each month."
