Here are two cases where links to a specific time code in SpaceX YouTube videos stop showing the intended moment because apparently SpaceX has gone in within hours or perhaps a day and shortened the videos.
In both cases the times are off by roughly ten minutes.
My first guess is that they are lopping off some of the pre-launch because its not interesting, but given the amazing interest the videos have generated and number of people including myself (e.g. What caused this shadow on Falcon 9 stage 2 w/Jason-3 before circularization burn? ) who comb them for educational goodies and "aha!"s, the idea that the videos are changing over time moves them farther from the data category and closer to the infotainment category.
It would be great to know what's gone. I'm not particularly looking for opinions or guesses - is there any factual accounts of what is removed, or are the original broadcasts (raw data) still available somehow?
