FoundryDB Edge Now Stays Up On Its Own: Per-Location HA and Autoscaling

The edge already puts a managed front end in front of your app: your own domain with an automatic certificate, caching, rate limiting, a WAF, and request analytics, served from EU points of presence. The piece you could not see was what happened when a machine behind that edge had a bad day. Today that piece is done. Every point of presence now runs as an active node with a hot standby, each location autoscales with your traffic, and if a whole location goes dark your requests are routed elsewhere and brought home when it recovers. None of it is something you configure.
