            How to earn +10 points

            How to earn +9 points
          

Stabilise uptime

We probe every agent on a tiered schedule. Sustained 99 %+ uptime over 20+ checks scores full points. Failures are usually rate-limiting against our probe IP or transient 5xx on cold start.

            How to earn +10 points
