This Service Level Agreement ("SLA") defines the performance commitments EstFlux makes to customers who have active, paid VPS hosting subscriptions. This SLA is incorporated by reference into EstFlux's Terms of Service.
This SLA applies to all active paid VPS instances on any EstFlux Boost plan. It covers the availability of your virtual server and associated network connectivity as measured from EstFlux's infrastructure boundary. It does not cover issues within your operating system, applications, or resulting from actions taken by you or your authorized users.
EstFlux guarantees a monthly uptime of 99.9% for all VPS instances. This translates to a maximum of approximately 43.8 minutes of allowed downtime per month.
Uptime is measured as the percentage of minutes in a calendar month during which your VPS instance was operational and reachable over the network, excluding scheduled maintenance windows.
If monthly uptime falls below 99.9%, you are eligible for service credits according to the table below. Credits are applied to your next invoice as a deduction — they are not issued as cash refunds.
| Monthly Uptime | Downtime (approx.) | Credit |
|---|---|---|
| 99.9% – 100% | < 44 min | No credit (within SLA) |
| 99.0% – 99.9% | 44 min – 7.3 h | 10% of monthly fee |
| 95.0% – 99.0% | 7.3 h – 36.5 h | 25% of monthly fee |
| 90.0% – 95.0% | 36.5 h – 73 h | 50% of monthly fee |
| < 90.0% | > 73 h | 100% of monthly fee |
Maximum credit in any calendar month is 100% of the monthly fee for the affected service. Credits do not carry over to subsequent months.
The following are excluded from uptime calculations and do not qualify for SLA credits:
Support is provided via email and the ticket system at estflux.com. Response time targets are:
| Priority | Description | First Response Target |
|---|---|---|
| Critical | Server completely unreachable, total service loss | < 4 hours |
| High | Significant performance degradation, partial outage | < 8 hours |
| Normal | Non-urgent technical questions, feature requests | < 24 hours |
| Billing | Invoice questions, payment issues | < 24 hours |
Response time targets are measured during business hours (09:00–18:00 EET, Monday–Friday). Critical issues are monitored outside business hours on a best-effort basis. Response time SLA is not subject to service credits; it is a target, not a guarantee.
EstFlux commits to the following network performance targets for the Estonian (Tallinn) location:
Network SLA credits follow the same structure as the server uptime credit table in Section 4.
To claim an SLA credit:
We reserve the right to reject credit claims that are submitted after the 14-day window or that cannot be verified against our infrastructure monitoring records.
Service credits described in this SLA are your sole and exclusive remedy for EstFlux's failure to meet uptime commitments. Credits do not constitute acknowledgment of fault or liability beyond the credit amount. This SLA does not modify or limit the Limitation of Liability provisions in EstFlux's Terms of Service.
