Cloudflare DEX Analytics Shows Missing Device Data Gaps

What happened

Cloudflare reported missing data in their CF1 Client DEX (Digital Experience) analytics overtime reporting on April 16. The issue affects device analytics data that enterprise teams use to monitor end-user performance and connectivity metrics. Cloudflare has identified the problem but has not yet provided a timeline for resolution or data backfill.

Business impact

Teams relying on Cloudflare DEX for user experience monitoring and performance reporting will have incomplete datasets for affected time periods. This creates blind spots in performance analysis and may impact SLA reporting or capacity planning decisions based on historical device analytics.

Background

Cloudflare's DEX analytics provide enterprise customers with visibility into end-user device performance, network connectivity, and application responsiveness. These metrics are increasingly critical for organizations managing distributed workforces and measuring digital experience quality across different locations and device types.

What this means for your team

Verify your DEX reporting dashboards and note any data gaps in your performance baselines for the affected period. Check if automated alerting or SLA calculations depend on this data stream and adjust reporting periods accordingly. Consider implementing backup monitoring through browser RUM or synthetic testing tools to reduce dependency on single analytics sources.

What to watch

Monitor Cloudflare's status page for updates on data restoration and root cause details. Teams should verify if historical data will be backfilled once the issue is resolved, as this affects trend analysis and reporting accuracy.
