You have to remember that the cloud is just a series of data centers owned by cloud providers. If you are Netflix, you’re not hosting Stranger Things for audiences in the US from the EU. You have a copy of it in both places and leverage AWS regions in each area to server geographically closer users (it’s typically called latency based routing). If the undersea cables are cut, the EU still watches Netflix because the content doesn’t need to travel undersea, it’s already in the EU, same thing in the US. The challenge comes in at the end of the month when people pay their Netflix bills and the banks needs to process international payments. End users are largely not impacted by direct service outages but big companies are.

Beautiful redundancy. My one true love
