Yes looks like something has just started going on with that service. I get the same thing and watching the browser it is also freezing quite regularly with a short spinning circle. I'm going to wait a week or so and see if it improves before looking to see what we can do at our end. It is HLS which is a pretty stock standard protocol and other large sites such as twitch arnt exhibiting this behavior.
