Cloudflare utilizes a globally distributed network and rolling updates. This means that updates are applied to individual data centers one at a time, rather than all at once. Traffic is automatically routed away from data centers undergoing maintenance, ensuring that users are served from healthy locations. This approach significantly reduces the overall impact of maintenance.
