It does **not** cover: * [Public RPC Endpoints](/node-apis/public-endpoints.md) — provided best-effort, without an SLA. * Scheduled maintenance announced in advance. * Issues within the blockchain networks themselves — chain halts, congestion, forks, or upstream protocol bugs. * Failures caused by the client's code or infrastructure, or by exceeding plan limits. * Force majeure events. ## Uptime measurement Uptime is calculated per calendar month: ``` Uptime = (total minutes − downtime minutes) / total minutes × 100% ``` Downtime is any period during which the endpoint is unreachable or consistently returns server-side errors, as confirmed by FastNode monitoring. ## Compensation If FastNode breaches this SLA — an unplanned incident on our side causes downtime beyond the guaranteed uptime — you can request, at your choice, either: * **A refund** for the unused period of your subscription, or * **A free service extension**, calculated as: ``` downtime (minutes) × 10 = free extension (minutes) ``` For example, 30 minutes of downtime entitles you to a 300-minute (5-hour) free extension of the affected node. ## How to claim Email **** within **30 days** of the incident. Include your account email, the affected network/endpoint, the time window, and whether you prefer a refund or a free extension — please don't send your full API key. We'll verify against our monitoring data and process your request. ## Dedicated & custom SLAs Dedicated clusters can include custom SLA terms tailored to your project — see [Services & Pricing](/advanced/services-pricing.md) or contact ****. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.fastnode.io/reference/sla.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
