What happened
Cloudflare has migrated its own blog — one of the highest-traffic technical blogs online — onto EmDash, the Astro-based content management system it has been building as an alternative to WordPress. The company rolled the change out gradually through a proxy Worker, shifting traffic from 1% to 100% with automatic fallback if anything broke, and redesigned the frontend with native light and dark mode and a new table-of-contents sidebar.
Why it matters for your business
Cloudflare is using its own highest-stakes property as the proving ground before EmDash reaches version 1.0, and the numbers back the pitch: the new backend, running on Workers with layered caching, held up under a k6-driven stress test peaking at 7,000 requests per second and absorbed a 28,000 RPS DDoS attack without customer-facing impact. For teams evaluating a WordPress replacement — especially ones already on Cloudflare — this is a load-tested reference deployment, not just a vendor claim.
What to watch next
EmDash is still pre-1.0. Teams considering it for a production content site should watch for the general release and treat Cloudflare's own blog as the benchmark to compare their own traffic patterns against.
