Availability
We target 99.5% availability a month, and publish what we measure.
Last reviewed 2026-10-13
Target
99.5% a month, about 3.6 hours of downtime. This is a target, not a service-level agreement, and there are no service credits.
Measured
| Period | Availability | Hours measured |
|---|---|---|
| 15–30 September 2026 | 99.993% | 384 of 384 |
Measured since 15 September 2026. Each month is added once it has ended.
How it is measured
Every 30 seconds, AWS Route 53 checks https://api.zeepler.com/v1/health from three AWS regions: US East, US West and Europe. That request goes through the same API gateway as the label API, runs a function and reads from the same database, so it fails if any of them does.
The figure is the average share of Route 53's checkers that found the API healthy over the period. A checker marks it unhealthy after three failed checks in a row, so an interruption shorter than about 90 seconds may not show. Hours with no check data are counted neither as up nor as down, which is why the table shows how many hours were measured.
What it does not cover
- It does not generate a label, so a fault in label generation alone would not show here.
- It measures whether the API answers, not how fast. We will publish a typical response time once we measure one.
- It checks from AWS, not from your network.
- It checks api.zeepler.com only. If your account uses another API host, that host is not included here.
