We asked Comcast for some guidance and details and were told via email to "stand by."
DSL Reports said this was coming back in May, noting that the MSO was mulling a charge of $15 for every 10 gigabytes cable modem subs (likely just a small fraction) go above the stated threshold. (See Comcast Caps Coming? )
When compared to other "metered" services, Comcast's threshold looks to be more generous, but there's no doubt that the MSO will have to contend with some significant backlash. (See Get Your Meter Running, Rogers Takes Internet Meter to the Masses, and TWC Tees Up Metered Internet Trial .)
It's not clear yet whether uploading will be capped as well or how this policy will complement Comcast's migration to a "protocol agnostic" platform. We'll keep you posted. (See Comcast Ready to Test New Traffic Cop, FCC Throttles Comcast, and FCC Puts Comcast on the Clock .)
Update: Comcast just posted the official details about this new policy. (See Comcast Amends 'Acceptable Use' Policy .) Story to follow.
