AT&T after a leak on Sunday confirmed that it will join other Internet providers in capping its service. Beginning on May 2, regular DSL subscribers will have up to 150GB per month, while those on its U-verse VDSL connections will have the same 250GB as a Comcast user. BBR was told overage fees of $10 for each extra 50GB of data will be in effect, but will only kick in for those who run over the cap three times, albeit over the duration of the account and not per year.
