While Apple CEO Tim Cook was unveiling the company's new iPhone 6, a live stream of the event crashed.

Those attempting to stream the event reported a Mandarin translation feeding in over Cook's voice, the video was behind, images were pixelated, caused browsers to crash, reports Business Insider.

Some angry viewers took to Twitter to complain about their experiences:

Amazing. #AppleLive stream is so bad, it just forced Safari to crash. Literally unwatchable.

Obviously this steam is reflecting the new quality control at #Apple. Selling my shares before the stock crash. /s #AppleLive $AAPL — Patrick Conan Doyle (@pcdoyle) September 9, 2014
