The Consumerist has uncovered a previously secret number: the monthly data download limit on Comcast internet connections:

Leaks: Comcast's Download Cap Is 200 GB, But Only In Areas With Subpar Networks

Comcast even has a system ready to go where if you exceed the limit a popup will ask you to purchase additional gigabytes, our source says. The graphical user interface is completely designed and everything, but Comcast hasn't deployed it, because they're waiting for either another ISP to do it first, or to figure out how to do it without angering their customers, whichever comes first.

I guess the first question that comes to mind for me is, "what would you expect the limit to be on an unlimited connection?" This question has come up before regarding data connections from Verizon Wireless and will surely come up many more times before companies are forced to publish a figure stating exactly what you're getting for your money. That shouldn't be too much to ask.

I found The Consumerists' story over on Geoff Daily's App-Rising blog. Geoff's been doing a great job covering broadband growth including fiber build outs and municiple approaches to broadband. If you're into that sort of thing, tell Geoff I said, "Hi."

Update: Matthew Ingram points out that wireless card plans from one popular dominant wireless carrier has a 250MB cap. 250MB? My email could chew through that in a month.
