Ferrisway is a Cloudflare Worker that serves as Ramp’s global routing layer, handling 100% of production traffic since January — including API requests, authorizations, webhooks, and AI-driven operations such as agent workflows and MCP tool traffic. It routes about half a billion requests each day, averages more than 5,000 requests per second, and processes roughly 10 TB of traffic daily. In this session, learn how Ferrisway makes fast edge routing decisions from cached configuration, while Gother — its cloud-deployed counterpart — provides a reliable source of truth on cache misses. See how Tail Worker–powered tracing maps Cloudflare execution to Gother spans for end-to-end visibility, how zero-traffic and forced-traffic testing make Worker rollouts safe, and how indirect mappings and explicit unresolved-destination behavior create a consistent, resilient routing layer at global scale.
