A Service Level Agreement, or SLA, is a formal commitment from a provider that defines the expected level of service, such as uptime, speed, or support response time. It often states what compensation a customer receives if the provider fails to meet these promises.
The provider sets clear, measurable targets, such as 99.9 percent uptime or a maximum average response time. These targets are written into the contract along with how they will be measured and reported. If the provider falls short of the agreed target during a billing period, the SLA usually specifies a remedy, such as service credits or a partial refund. Customers can review uptime reports or dashboards to confirm the provider is meeting its commitments.
This is largely a plan and configuration choice, not a technical limitation.
USER-sla-session-task01Everything lives in the username -- add "sla" to any proxy credential to apply sla to a single task. Swap "task01" for a new label to spin up an independent, isolated identity.
KnoxProxy sticky sessions persist up to 30 minutes on residential (60 on mobile), and the window refreshes with activity.
Each session or connection label gets its own exit, so parallel identities never collide.
This costs nothing beyond bandwidth -- successful responses are billed, not the session or connection itself.
Run as many parallel sessions or connections as the job needs -- concurrency is not capped on any plan.
A proxy provider SLA promises 99.9 percent uptime and issues account credits automatically if that target is missed in a given month.
An SLA gives customers a clear, enforceable standard instead of vague promises about reliability. Checking the SLA before signing up helps buyers understand what protection they actually have if service quality drops.
SLA is a plan-level or configuration-level concept that determines how proxy resources get allocated across your jobs. It is a billing and management concern, not a protocol detail.
Most SLAs specify a clear remedy for a missed target, such as automatic service credits applied toward a future bill, as outlined in the contract terms. The exact percentage thresholds and how the shortfall gets measured vary by provider, so the agreement should be read carefully before signing up.
No, many budget or trial-tier plans skip a formal SLA entirely, offering no enforceable uptime or performance commitment at all. Business and enterprise plans are far more likely to include one, since larger customers typically negotiate specific service guarantees before committing to a contract.
