We’ll start with an overview of some of Signal’s biggest infrastructural costs—what we pay for the utilities and services that let Signal reach you. These include the temporary storage of end-to-end encrypted data for message delivery; the global server network that processes billions of requests every day; the registration fees that cover the delivery of verification codes during the sign-up process to help verify phone numbers and prevent spam accounts; the bandwidth that is required to efficiently route end-to-end encrypted messages and calls around the world; and some of the additional services that keep everything running smoothly. We’ll dive into each of these in more detail, but here’s a quick breakdown:
Storage: $1.3 million dollars per year.
Servers: $2.9 million dollars per year.
Registration Fees: $6 million dollars per year.
Total Bandwidth: $2.8 million dollars per year.
Additional Services: $700,000 dollars per year.
Current Infrastructure Costs (as of November 2023): Approximately $14 million dollars per year.
