# Fair Usage Policy

To ensure stability of provided services and prevent any potential traffic abuse, Oxylabs limits the concurrent sessions of provided Dedicated ISP proxies. The available concurrent sessions depend on the amount of traffic used per 1 Dedicated ISP proxy during a billing cycle:

* **Until 100 GBs of usage per 1 Dedicated ISP proxy in a month is reached,** up to 100 concurrent sessions are available per 1 purchased Dedicated ISP proxy (For example, purchasing 100 Dedicated ISP proxies means that 10,000 concurrent sessions will be available until 10,000 GB of usage is reached);
* **If 100 GBs of usage per 1 Dedicated ISP proxy is reached,** the available concurrent sessions are reduced to 10 concurrent sessions per 1 Dedicated ISP proxy for the remainder of the ongoing billing cycle (For example, purchasing 100 Dedicated ISP proxies and reaching 10,000 GB of usage means that 1,000 concurrent sessions will be available until the end of the current billing cycle).

Proxy usage is tracked automatically and an email notification is sent when 80% and 100% of the data allowance is reached. Once 100% of the fair usage limit is reached, the concurrent session limit is applied automatically.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers.oxylabs.io/products/proxies/dedicated-isp-proxies/self-service/fair-usage-policy.md?ask=<question>&goal=<endgoal>
```

`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.
