Data and infrastructure

Our platform uses multiple Cloud Infrastructure providers (IaaS) to run Flat. To provide the best performances, security, and service, these providers and datacenters are located in multiple countries. We also replicate data across multiple countries.

Domain names

Allow these domains for Flat and related services:
