Uptime and efficiency
Our own measurement of our own service — whether the site answered, how fast, how often a visitor was interrupted — against standards we print and can miss. API latency and browser interruptions have been counted since 2026-10-12; heartbeats since earlier.
1 of 6 measured standards met · checked 2026-10-21 18:12 UTC
| Standard | Target | Measured | Status |
|---|---|---|---|
Site answers its own heartbeat (home, record, API health …) Share of 10-minute heartbeats in which every core probe returned. 99.9% leaves 43 minutes a month. | >= 99.9% / 30d | 96.77% | MISSED |
API calls that failed on our side (HTTP 5xx) A 5xx is our fault. 4xx (bad key, not found, rate-limited caller) is not counted. | <= 0.5% / 7d | 2.712% | MISSED |
API answer time, 95th percentile Approximate, from a latency histogram. Receipt builds that read a dozen agencies run longer by design and show up as stalls. | <= 1500ms / 7d | 10,000ms | MISSED |
API calls slower than 3 seconds A stall is a wait, not a failure. Most stalls are an official source answering slowly; we count them against ourselves anyway. | <= 1% / 7d | 8.245% | MISSED |
Visitors interrupted (script error or failed call, per 100 page views) The browser posts a one-line report when a script throws or a call to us fails. No visitor is identified. | <= 0.5% / 7d | 12.809% | MISSED |
Hourly receipt build completes The sentinel builds one real receipt each hour. 'Completes' means a receipt was written — sources that did not answer are recorded inside it, not hidden. | >= 99% / 7d | 100% | met |

Each probe, last 30 days
Each heartbeat is one probe of the core pages and API from outside, every 10 minutes; a run with any failed probe counts as down for the whole 10 minutes.

Official sources, last 7 days — their availability, not ours
An official source that did not answer is written on the receipt as 'did not answer' — never as 'no record'. This is the sources' availability, not ours; it is here because a slow source is still a wait for the customer.
