This is to ensure that for a particular host (youtube or facebook) the resolved DNS host is a geographically local server. This is how large video networks are capable of providing access to videostreams for so many people. The content is replicated to geographically local servers.
I suspect BM took the decision to fix these in order to stop complaints later on.
(Just a theory).
Thank you Andy for your post which helped me understand the problem I am currently having with a Web Presenter 4K. I will explain it below.
We are using a Blackmagic Design Web Presenter 4K to stream videos via our Mux account. From our office network, we have no problem. It works perfectly. But from the network of one of our customers, it is impossible to establish a connection to the Mux servers.
The only difference is that our customer's network has a DNS proxy, blocking all external DNS requests. When we try to stream from their office to youtube, it works perfectly. But, when we try to stream to Mux, it doesn't work. According to our customer's technical team, it seems that the Web Presenter device only sends DNS requests. Last thing: a "ping global-live.mux.com" returns us the IP address 34.91.55.198 from a PC connected to our customer's network.
Can you explain why the Web Presenter 4K behaves differently, in the same network context, when streaming to YouTube and MUX?
