What the states mean
- Working
- Checked on schedule.
- Late
- No successful check for longer than expected.
- Failing
- The latest check failed; the last good data is kept.
- No data yet
- Never collected successfully.
A source is late after 3 expected checks pass without success, and never sooner than 20 minutes. While a source is late or failing, pages keep showing the last good data with its time, and withhold it once it passes the limits on the methodology page.
