Why Youtube Buffers: the Secret Deals That Make—And Break—Online Video When Isps and Video Providers Fight Over Money, Internet Users Suffer
Why YouTube buffers: The secret deals that make—and break—online video When ISPs and video providers fight over money, Internet users suffer. Lee Hutchinson has a problem. My fellow Ars writer is a man who loves to watch YouTube videos— mostly space rocket launches and gun demonstrations, I assume—but he never knows when his home Internet service will let him do so. "For at least the past year, I've suffered from ridiculously awful YouTube speeds," Hutchinson tells me. "Ads load quickly—there's never anything wrong with the ads!—but during peak times, HD videos have been almost universally unwatchable. I've found myself having to reduce the quality down to 480p and sometimes even down to 240p to watch things without buffering. More recently, videos would start to play and buffer without issue, then simply stop buffering at some point between a third and two-thirds in. When the playhead hit the end of the buffer—which might be at 1:30 of a six-minute video—the video would hang for several seconds, then simply end. The video's total time would change from six minutes to 1:30 minutes and I'd be presented with the standard 'related videos' view that you see when a video is over." Hutchinson, a Houston resident who pays Comcast for 16Mbps business-class cable, is far from alone. As one Ars reader recently complained, "YouTube is almost unusable on my [Verizon] FiOS connection during peak hours." Another reader responded, "To be fair, it's unusable with almost any ISP." Hutchinson's YouTube playback has actually gotten better in recent weeks. -

Media Release
Media release 12 December 2013 Bill Morrow appointed NBN Co CEO Global telecommunications executive Bill Morrow will steer the National Broadband Network through the next stage of its development. The Vodafone Australia CEO has been appointed Chief Executive Officer of NBN Co Limited, the company responsible for delivering Australia’s nationwide fixed-line broadband upgrade. He will join the company in the New Year and will be based in Sydney. Mr Morrow’s appointment by the Board of NBN Co comes as the company lays out the framework for delivering very fast broadband to Australian homes and businesses sooner and at less cost to taxpayers than previously was the case. The new approach is contained in the Strategic Review of the NBN which the company presented to the Government today. Announcing the appointment, NBN Co Executive Chairman Dr Ziggy Switkowski said: “I am delighted that a senior business leader of the calibre of Bill Morrow has agreed to accept the challenge of delivering the long-promised upgrade to Australia’s broadband infrastructure. Bill’s experience extends not only to running major telecommunications businesses but, from his time at Clearwire in the United States, also building a large scale network. He possesses the right mix of talent, experience and deep knowledge of the telecommunications industry to ensure NBN Co can get the job done.” Mr Morrow said: “I staunchly believe that this important initiative, done right, will provide a boon to the nation’s economy. The digital revolution is picking up speed. With the right infrastructure and industry collaboration, Australia will reap the benefits for decades to come. -
