No, AT&T hasn't created internet fast lanes. But...
Is AT&T carving out lanes on the internet and offering the speediest service to the highest bidder, while leaving all other internet traffic relegated to "slow lanes"? Not exactly. AT&T hasn't introduced a new service that explicitly prioritizes one type of traffic over another. But that doesn't mean that it isn't offering other services that might run afoul of the strict network neutrality restrictions that are set to expire soon.
