- postmortem Nov 19, 2025, 01:03 PM UTC
One of our core 3rd party dependencies Cloudflare experienced an outage and failed to deliver core network traffic. More about the Cloudflare incident can be read in their [Postmortem](https://blog.cloudflare.com/18-november-2025-outage/). The Cloudflare outage impacted all of our customer’s domains which are routed through Cloudflare by default causing all of our customer’s websites to be unavailable. Additionally, the Xperience Portal \(also routed through Cloudflare\) was made unavailable which not only impacted the Xperience Portal UI but also the Deployments API. Cloudflare eventually recovered their services and we did not record any further availability drops.
