For some reason this video is blocked by the filter our system uses (IBoss clean video search). I’m not sure why. I found a work around for this time, but just thought I would mention it in the event you can get it added to the “clean” list. It is a good video.
Thanks for the heads up. We’ve added that video online at studio.code.org/s/csd1. When updates go live in the next day or so you’ll be able to find a link there to our alternate player which allows you to watch the video without worries about YouTube filters.
Let us know if you still run into issues and thanks for checking in!
