That's a really great point about multi-CDN architectures.

Partly because big parts of WebRTC are not standardized (session setup signaling, of course, but also in practice lots of necessary state management) it's a little bit hard to imagine how to build an equivalent for WebRTC.

Relatively recently, I would have said that our experience running large-scale WebRTC stuff in production made "core" infrastructure failure relatively low on our list of concerns. The two components of the last mile connection, on the other hand, are always a huge pain point because of the long tail of bad ISPs and bad Wifi setups.

However ... many of us who try to deliver always-available video services got something of a wakeup call in November and December last year when AWS had two pretty big outages two months in a row.
