Thanks for the plug. I'm the author of the failover piece. Happy to answer questions.

"When we failover US-East, we send traffic from the Eastern U.S. to the EU and traffic from South America to US-West. "

Interesting that you shift US-East to the EU. Any more color on why that direction, versus say, US-West? Like maybe less common components in AWS? At face value, it seems like an odd choice.

See slide 5 of this presentation: https://www.slideshare.net/mobile/InfoQ/chaos-kong-endowing-...

That "this is what success feels like" slide is mind-boggling. All Netflix clients on all platforms on all devices simultaneously react.

I can only imagine what debugging misbehaving clients looks like, it's got to be north of 1,000 hardware/software profiles.

Basically because their peak usage hours don’t overlap as much as US-East and US-West.
