It appears fine for me, and some others, but some of the web devs also were able to verify some issues where it would play directly by URL but not in the player.
Someone is looking into it.
Do you have an ad-blocker enabled? Could you try without?
The video is served by a CDN, the URLs are randomly generated and it seems that this one video unfortunately has the words /ad/ in the URL. So it gets flagged as advertisement even though it's legit content.
Updated a bunch of media assets with new paths starting with something other than ad, so the training should be working now even with the adblockers (only tested with mublock though).
Also updated the way upload paths are generated (53c502ee15, this is possibly one of the silliest commits I've seen in my entire life).
