Uptime history
How to read the daily bars and the uptime percentage on a status page.
See it
This is the real uptime block of a status page, with sample data. Pick a history and point at a bar to see that day.

What the bars mean
- One bar = one day. The last bar is today, so far. Wide screens show 90 days, tablets 60, phones 30.
- Green: every check passed. Green with a red part: some checks failed; the red part is how much. Red: every check failed.
- Grey: no data for that day (for example before the page existed).
- Below the bars, the strip of the last 24 hours shows hour by hour.
How the percentage is worked out
Passed checks divided by all checks over the days shown. A day with 720 checks and 8 failures is 98.9% for that day; over 90 days, a few minutes down barely moves the total.
On a page in Manual mode, days without incidents count as 100%. Incidents you post as an outage count as downtime: see Incidents and uptime.
