Thanks for your reports about YouTube, YouTube TV and YouTube Music access issues. We're working on resolving this and will let you know once fixed. We apologize for any inconvenience this may cause and will keep you updated.
The farthest I've gotten in the past hour-ish is I can search for a video and click on it. Once I do, nothing around the video itself loads (suggestions, video title, comments) and the video itself shows static and "an error has occurred".
