No published SLA during early access
Start with what this page is not. Runix Router is in early access, and there is no published SLA, no uptime percentage and no historical availability chart — because publishing one would mean standing behind a number we have not operated long enough to promise. What follows is how the system behaves, which is a different and more useful claim.
Failure is expected, so it is designed for
Model providers degrade. They rate-limit, they time out, they return errors in bursts, and they have bad hours that have nothing to do with your code. A router that simply forwards requests passes every one of those through to your users.
- Errors, rate limits and timeouts trip a circuit breaker. The request is re-issued to a healthy alternative under a retry budget, so a provider's bad hour does not become your outage — and the budget exists so that retrying never becomes its own outage.
- Mid-stream failures are re-issued too. A failure part-way through a streamed response is the awkward case most integrations get wrong; the mechanics and the edge cases are in how streaming failover works.
- A degrading provider leaves the rotation before it drags your latency, and comes back when health checks pass.
Why the key matters here
Failover is only safe if the alternative is one you would have chosen. Routing preferences are set per key server-side — cheapest acceptable, latency-first, provider allowlists — so when the router moves a request, it moves it inside the boundary you defined rather than to whatever happened to be up.
What you can verify yourself
Every response carries a request id, and errors use a structured envelope, so a failure can be traced to a specific call rather than argued about. The Router quickstart documents the error shape and the failover semantics in full.
What is not here yet
A continuously updated public status feed is not live. When it is, it will report measured availability rather than an aspiration. Until then, the honest answer to "what is your uptime" is that we will tell you what we have measured for your workload, and we will not quote a number we cannot evidence. If reliability guarantees are a procurement requirement for you, say so during intake and we will tell you plainly whether early access fits.
