Data Retention
Blimey retains different types of data for different periods to balance detail with storage efficiency.
Individual check data — 3 days
Each individual uptime check (with status, response time, status code, and timestamp) is kept for 3 days. After that, the individual records are automatically cleaned up.
This means the detailed bar chart and recent checks table show data from the last 3 days at most.
Daily summaries — kept long-term
Every day, Blimey creates a summary of your store's performance including:
- Total checks, successful checks, failed checks
- Average, minimum, maximum, and P95 response times
- Daily uptime percentage
These summaries are kept indefinitely and power the long-term trend charts (Response Time Trends and Daily Uptime).
Incidents — kept long-term
All incident records (outages with start time, end time, and duration) are kept indefinitely for your records.
What this means for you
- Short timeframes (1h, 6h, 12h, 24h, 3d): You'll see individual check data as bar charts
- Longer timeframes (7d, 14d, 30d, 3mo+): You'll see daily trend data. Individual checks from beyond 3 days won't appear in the bar chart, but the trend charts show aggregated data for the full period.
