We use NS1 for reliable DNS serving

Server Hosting & Replication

We use in the US/EU and Scaleway in the EU for our Server Hosting.

Each location is setup in the following way:

  • BGP based load-balancers at the border
  • Application servers serving Signed Requests, API calls and Webhook calls
  • Replicated Database servers

  • By default data is replicated between both Chicago and Paris.
  • ResinFiles can be setup in any jurisdiction
    • For example financial organizations tend not to want their data escape their own country. * not that we store any anyway
  • Data is sent encrypted over TLS using ECDSA keys
  • If Paris servers go down then they’ll automatically swap over to Chicago.
