If you were to sum up what @YouTube is supposed to do, it'd probably boil down to "Share videos between users." Currently, I have a video that won't load past 3:52. No other video on the platform is affected. No other website is affected. Youtube no longer streams video
That's odd, could you file a feedback report with these steps: https://goo.gl/1ckkO5 ? We review all the feedback sent to us, but YouTube doesn't necessarily respond to every single one. We use the info to identify and fix issues, as well as track requests and make improvements.
