Ladies and gentlemen, the all-you-can-eat buffet is now closed. After capping wireless data plans without too much uproar, telco AT&T will begin doing the same with DSL and U-verse customers effective May 2.

DSLReports.com is reporting that AT&T will begin implementing data caps on their DSL and U-verse customers beginning on May 2, with terms of service change notices going out March 18 to March 31. After receiving a leaked copy of the company’s plans, the website confirmed the change with AT&T spokesman Seth Bloom.

AT&T DSL customers will now be capped at 150GB per month, while U-verse customers can use up to 250GB per month (presumably because the service includes internet, voice and television, all shared with the same connection). If you exceed those usage caps three times, you’ll be slapped with overages to the tune of $10 for every additional 50GB of data. The overage “three strikes” rule is not per month, but based on your total service usage after the caps kick in on May 2.

Much like the wireless data caps before them, AT&T claims these broadband caps will only affect two percent of their customers. The telco claims that the average DSL customer uses “around 18GB a month,” which means that two percent are consuming “a disproportionate amount of bandwidth.”

AT&T will “proactively notify customers when they exceed 65 percent, 90 percent and 100 percent of the monthly usage allowance,” as well as provide tools for customers to monitor their monthly data usage and even see their historical usage for comparison.

"We are committed to providing a great experience for all of our Internet customers," AT&T claims. "We will communicate early and often with these customers so they are well aware of their options before they incur any additional usage charges. Importantly, we are not reducing the speeds, terminating service or limiting available data like some others in the industry."

While that may be the case, broadband data caps do not bode well for companies such as Hulu, Netflix and even Apple’s own iTunes, who have the potential to gobble up gigabytes of data in just a few hours of watching content -- not to mention, the U.S. still trails far behind other countries where internet speeds are concerned.
