How to read a hosting provider's SLA: median, p95, and compensation

This Habr article provides a detailed guide on interpreting hosting provider Service Level Agreements (SLAs). The author notes that the availability percentage is only the tip of the iceberg. To properly assess service reliability, one must consider the measurement window, data sources, exclusions, and the specific procedures for claiming compensation. The article explains why it is crucial to focus on metrics like the median and p95 rather than simple averages, which often mask brief outages. Because terminology and calculation formulas vary significantly between providers, the author urges readers to carefully review every version of the contract. Understanding these nuances allows businesses to better evaluate risks and select a provider whose guarantees align with the project's actual needs, rather than just looking attractive on marketing pages.
