Methodology

Every minute, we create a Kosa8 sandbox, run a small workload in it and destroy it. A check fails if any step errors. Each counted failed check counts as 1 minute of downtime out of the 525,600 minutes in a year. Checks our scheduler skipped never count against a provider. Manually excluded failures appear as “Not counted” with a reason and do not affect uptime or incidents. All times are UTC.
