By Marina Lopes NEW YORK (Reuters) – Netflix Inc, the video streaming service, on Monday criticized ATTs high-speed fiber network as inadequate and slow, while renewing its call for ATT to interconnect directly with Netflix. Netflix made the remarks in a letter to shareholders on its first-quarter results. The company has been calling for greater protections for open Internet rules, also known as net neutrality, which require Internet service providers to give consumers equal access to all lawful content without restrictions or tiered charges. Netflix, in a letter signed by its chief executive, Reed Hastings, and chief financial officer, David Wells, said ATTs fiber-based U-verse service has lower performance than many DSL Internet service providers.
