Daily p50, p90 and p95 of the retrieval time to first byte (TTFB) or time to last byte (TTLB) for the selected provider at the probe location, in seconds. Use the selector to switch between TTFB and TTLB. Computed over successful retrieval checks only. Failed or timed-out retrievals have no first-byte or last-byte time.
The dashed line shows the number of samples each day, plotted against the right axis. Tail percentiles (p90/p95) capture the slow retrievals that median latency hides.
For more information about the retrieval checks, see Retrievals.
