Cloudflare doesn't live on a detour.
It doesn't live at a separate inspection point.
Cloudflare lives in the path.

The Decision

HCA has already chosen to modernize.

It has already chosen to expand digital access.

It has already chosen to move critical workloads to the cloud.

It has already chosen to make AI part of the future of healthcare delivery.

The remaining decision is whether the foundation underneath those initiatives reduces complexity or adds to it.

Cloudflare is asking HCA to evaluate that foundation before today’s architecture becomes tomorrow’s constraint.

Background

Cloudflare’s Origin Story

Built as a System, Ready for What Nobody Saw Coming

The Cloudflare story starts in 2004 with a question: where does email spam actually come from? To answer it, the founders built Project Honey Pot, a distributed system that let any website owner plant tracking traps for spammers and malicious bots, mapping their behavior across the internet in real time. Over five years, thousands of websites in 185 countries joined.

The dataset grew rapidly. And users kept pushing for more capability — “don’t just track the bad guys. Stop them.”

What the Founders Actually Built

Lee Holloway didn’t build another web proxy. He built a globally distributed reverse proxy layer that ran the same software stack on every machine, everywhere, simultaneously.

The physical infrastructure was unremarkable: commodity x86 servers in colocation facilities around the world, nothing exotic.

The radical part was the software architecture and what it was designed to do.

Rather than sending traffic to a specialized system for caching, then another for security, then another for routing, Lee built a unified packet-to-application processing pipeline where a request arrives, gets parsed, hits security logic, gets routed, and gets served, all inside the same system.

Combined with anycast routing (where every Cloudflare location shares the same IP address and the internet automatically routes users to the nearest one), this meant that any Cloudflare server anywhere in the world could handle any request for any customer.

Why didn’t everyone build it this way?
Because it is brutally hard.

It required writing high-performance networking code to make security fast enough not to slow everything down. It required solving distributed systems problems at a scale most companies avoid: pushing policy changes globally in seconds, keeping every location consistent, failing over gracefully if parts of the network go down.

And it required walking away from the business model most networking companies were built on: selling high-margin hardware appliances.

Cloudflare’s entire bet was that if you own the network, you don’t need to sell boxes.

Cloudflare didn’t build services on top of a proxy, it built a network. That difference is now visible in every enterprise conversation about what infrastructure can actually support the next ten years.

Where Cloudflare Stands Today, and Why AI Changes Everything

By 2025, Cloudflare was processing traffic for roughly 20% of all websites on the internet. But revenue and growth are not the real story. The real story is architectural timing.

AI agents are not like traditional software. Traditional software runs in predictable locations, on predictable schedules, talking to known endpoints. AI agents are autonomous. They make decisions, call APIs, spin up processes, and talk to other agents. Constantly, globally, simultaneously, and at a scale that was unthinkable five years ago.

They need infrastructure that is globally distributed, low-latency, secure by default, and instantly available, with no servers to provision and no regions to choose.

Cloudflare has been building exactly that infrastructure for fifteen years, without knowing AI agents would need it.

That foundation was not built for AI. But it turns out, building for the hardest problems on the internet (global scale, millisecond latency, consistent security everywhere, no boxes) is exactly what AI needs. Cloudflare did not predict AI. They just built the right thing, and AI arrived.
