Case Study: Latvia Ministry of Health achieves smooth national COVID-19 vaccine registration and handles peak traffic with Cloudflare Project Fair Shot

Latvia’s Ministry of Health smoothly deploys COVID-19 vaccine registration with the help of Project Fair Shot

Latvia’s Ministry of Health faced the task of rolling out a national COVID‑19 vaccine registration system with a small eight‑person task force overseeing appointments, logistics, and public outreach for a population of about two million. The team expected—and immediately encountered—massive surges in traffic after encouraging citizens to pre‑register (10% signed up within weeks), risking backend overload during phased, randomized appointment scheduling.

Cloudflare’s Project Fair Shot, using the Waiting Room, acted as a virtual gateway so the team could throttle traffic, monitor requests in a control room, and tune parameters live. The solution handled peaks of thousands of requests per second, preserved users’ place in line, masked backend outages, avoided costly infrastructure upgrades, and delivered a smooth, well‑received launch with on‑the‑fly optimization and positive public feedback.
