Stability ranking & reading the charts
Stability is the "post-mortem" page. For the chosen number of days it shows:
- Site Uptime ranking: least-stable sites first (top 40 by default) with uptime percentages.
- Incident cause distribution: incident share by type over the period — "was it their server or the link" is decided from here.
- Daily incident count & recovery time: taller bars, worse days; recovery duration shows how long incidents dragged on.
- Hour-of-day distribution: which hour of day incidents cluster in — a consistent peak usually means a capacity issue.
How to use it
Review weekly: if a site keeps failing in the same hour, it's capacity or a scheduled job; if ssl dominates the cause distribution, your certificate-renewal process needs work.
