Rubicon guarantees 99.9% monthly uptime on every provisioned server — with a service credit program when we fall short. No multi-zone requirement. No extra configuration. Every server, out of the box.
AWS and Google Cloud advertise 99.99% uptime — but only for workloads deployed across multiple availability zones. For a standard single-server deployment, the real SLA figures tell a very different story.
| SLA Metric | AWS | Azure | Google Cloud | Rubicon |
|---|---|---|---|---|
| Advertised Headline SLA | 99.99% | 99.9%–99.95% | 99.99% | 99.9% |
| Applies To | Multi-AZ deployments only | Single VM (Premium SSD) | Multi-zone deployments only | Every server, single site |
| Single-Server SLA | 99.5% | 99.9% (matches Rubicon) | 99.5% | 99.9% ✔ |
| Allowable Downtime / Year (single server) | ~3.65 days | ~8.7 hours | ~3.65 days | ~8.7 hours |
AWS single-instance SLA of 99.5% and Google Cloud single-instance SLA of 99.5% based on published SLA documentation. Customers should independently verify current SLA terms with each provider.
| SLA Level | Max Downtime / Month | Max Downtime / Year |
|---|---|---|
| 99.9% — Rubicon | ~43 minutes | ~8.7 hours |
| 99.0% | ~7.2 hours | ~3.65 days |
| 95.0% | ~36 hours | ~18.25 days |
Uptime is measured from Rubicon's network edge to the server's network interface and is monitored continuously. A server is considered unavailable when it fails to respond to network connectivity checks for two or more consecutive minutes.
Scheduled maintenance windows, with a minimum of 48 hours advance notice to the customer, are excluded from uptime calculations. Rubicon will provide advance notice via email to the primary account contact.
If Rubicon fails to meet the 99.9% monthly uptime commitment for any individual server, the customer is entitled to a service credit applied to the following month's invoice.
| Monthly Uptime Achieved | Downtime in the Month | Service Credit |
|---|---|---|
| 99.0% to < 99.9% | ~43 minutes to ~7.2 hours | 10% of affected server fees |
| 95.0% to < 99.0% | ~7.2 hours to ~36 hours | 25% of affected server fees |
| < 95.0% | More than ~36 hours | 50% of affected server fees |
