the broadband speeds of New York are under investigation

the broadband speeds of New York are under investigation ,

the office of New York Attorney General investigates whether Internet providers are over-charging consumers for broadband speeds they announce but never deliver. According to reports of Bloomberg and Reuters, letters were sent to three ISPs in New York last week - Verizon, Time Warner Cable and Cablevision - asking them to disclose how they advertise speed Internet for customers and the results of any internal test of their services.

"New Yorkers deserve the Internet speeds they are paying for," said Attorney General Eric Schneiderman. "But it turns out, many of us can pay for one thing and do another. Families pay a huge cost already for Internet access in New York, I will not tolerate a situation in which they receive not what they were promised. "

slow speeds could be caused by business disagreements, not technical difficulties

According to Bloomberg lead attorney Schneiderman wrote Tim Wu in letters is "specifically concerned about the disruption of the consumer experience caused by interconnection disputes." These conflicts occur when the network of a company joins another, with a study last year suggested that interconnection issues have a "very negative impact" on Internet performance. The same study notes that these problems are caused by disagreements between ISPs -. No technical bottlenecks choke

Wu, who is perhaps best known as an advocate of net neutrality, and who joined the office Attorney General last month, reportedly warned Verizon, Time Warner Cable and Cablevision that the Internet speed they offer "can differ quite far from the advertised speeds for making false advertising." The three companies have denied that they are shortchanging customers, and have until November 8 to provide the requested material.
