Zero CIRR Ended Plays

Zero CIRR Ended Plays is the percentage of ended plays that experienced no connection-induced rebuffering during the selected interval.

Updated 2026-07-27 zero-connection-induced-rebuffering-ratio

CIRR uses nonseekRebufferingTime as the total time during which the reported player-state is "buffering", and does not include the buffering time before the first frame of a video is displayed, buffering following user-initiated seeks (S1) and any paused time. If rebuffering starts 10 seconds or more after seek start, this rebuffering is also counted as connection induced rebuffering. Otherwise, it is counted toward seek-induced rebuffering. For more details, see Connection Induced Rebuffering Ratio.

Zero CIRR Ended Plays % is available as a time series for the selected period in the Trends All Metrics and Diagnostics.

Dimensions Use dimensions to filter this metric by metadata segments for enhanced performance analysis. For example, limiting data to specific ISP and player dimensions can narrow your analysis to the best performing provider and player types.
Diagnostics

The Diagnostic page displays a time series of the percentage of ended plays with zero CIRR, sorted by Attempts, Plays, Concurrent Plays, and Ended Plays. You can also apply Filters to focus on the most high-performing plays, for example by CDN/Resource and ASN, and which assets. For more information about diagnosis with this metric, see Diagnosis.

AI Alert Support No.
Metric Adjustments

None. Micro rebuffering, continuous rebuffering less than 200 milliseconds, is not excluded.
