Hey @YouTube what's with errors? I can only play videos if I logged into gmail account. Not cool. cc @TeamYouTube/@Googlepic.twitter.com/uLIeQ2HBDr
You can add location information to your Tweets, such as your city or precise location, from the web and via third-party applications. You always have the option to delete your Tweet location history. Learn more
Based on reports, and YouTube's response, I would guess one of their CDN/Content Servers is/was misbehaving, and you just happen to get that server when logged out. I was able to play the channel intro video both logged in and incognito. (probably fixed by now)
