Cloudflare One Appliance, Cloudflare One, Cloudflare WAN - Post-quantum encryption support for Cloudflare One Appliance

Cloudflare One Appliance version 2026.2.0 adds post-quantum encryption support using hybrid ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism). The appliance now uses TLS 1.3 with hybrid ML-KEM for its connection to the Cloudflare edge. During the TLS handshake, the appliance and the edge share a symmetric secret over the TLS connection and inject it into the ESP layer of IPsec. This protects IPsec data plane traffic against harvest-now, decrypt-later attacks. This upgrade deploys automat

Workers - Workers are no longer limited to 1000 subrequests

Workers no longer have a limit of 1000 subrequests per invocation, allowing you to make more fetch() calls or requests to Cloudflare services on every incoming request. This is especially important for long-running Workers requests, such as open websockets on Durable Objects or long-running Workflows, as these could often exceed this limit and error. By default, Workers on paid plans are now limited to 10,000 subrequests per invocation, but this limit can be increased up to 10 million by setting

Workers - Improved React Server Components support in the Cloudflare Vite plugin

The Cloudflare Vite plugin now integrates seamlessly @vitejs/plugin-rsc, the official Vite plugin for React Server Components. A childEnvironments option has been added to the plugin config to enable using multiple environments within a single Worker. The parent environment can then import modules from a child environment in order to access a separate module graph. For a typical RSC use case, the plugin might be configured as in the following example: export default defineConfig({ plugins:

The Container paradox: Why the Inference Cloud Demands a “Decoupled” Database

Kubernetes has won the cloud-native war for a reason: it’s one of, if not the most powerful tool we have for scaling applications and ensuring they stay up when unexpected things happen. But as we move into the era of the Inference Cloud, we’ve fallen into a trap. We’ve become so enamored with “everything-as-code” that we’re forcing our most sensitive data inside the cluster. At DigitalOcean, we see thousands of enterprises building on DigitalOcean Kubernetes (DOKS). The most successful ones hav
