   Type: Incident Duration: 1 hour and 40 minutes Affected Components: Device Fingerprinting Nov 18, 12:10:00 GMT+0 - Resolved - During [Cloudflare's 2025-11-18 incident](https://blog.cloudflare.com/18-november-2025-outage/), loading of Device Fingerprinting's frontend script was inaccessible for customers using a custom domain powered by Cloudflare. Any client that normally would have been fingerprinted during this time would have failed to do so and received no telemetry. Clients that had already loaded the script before this time period were unaffected. Nov 18, 11:30:00 GMT+0 - Investigating - We are currently investigating this incident.
