PlanetScale is built on Vitess ( https://vitess.io https://vitess.io ) which actually uses MySQL as the backing store, and Vitess has been deployed at Youtube, Slack, and a bunch of other companies for years ( the first commits date back to September 2010 ). It is just about as rock solid as you can get.
