You need the privacy and control of hosting your own data, but you cannot afford the anxiety of wondering if your critical communications are actually reaching their destinations. Existing cloud relays are built for enterprise marketing blasts, lacking the simple reputation dashboards and developer-friendly onboarding that individual infrastructure enthusiasts require.
