+title: "Improved reliability for account-wide Web Analytics dashboards"
+description: "Web Analytics introduces performance optimizations and safety thresholds for accounts tracking a large volume of websites."

+
+Cloudflare Web Analytics (Real User Monitoring) has rolled out performance optimizations to significantly improve the stability and loading speed of account-wide dashboards.
+
+For large accounts monitoring hundreds to thousands of websites, loading the aggregate account-wide view would often fail, running into timeouts or unexpected interface errors due to the massive scale of parallel query processing. This update optimizes how high-volume multi-site data is queried to reduce errors and provide a snappier dashboard experience.
+
+As part of this optimization, Cloudflare is introducing a safety guardrail for a minority of complex accounts. If your account contains **more than 1,000 active sites**, a contextual warning will now appear on your account-wide Web Analytics view.
+
+This warning states that the aggregate view _may_ include historical beacon data from recently-deleted sites alongside active properties.
+
+If your workflow requires absolute, strict accuracy focused only on active sites, use [the filtering options](/web-analytics/configuration-options/filters/) to select the relevant site(s).
