# Fast purging At Transparent Edge, by default, we use fast purging to instantaneously purge content. This system lets us invalidate content on all Transparent Edge nodes in under two seconds. #### How do we implement fast purging? It’s quite simple. All Transparent Edge nodes are subscribed to a fanout queue in an internal Rabbit MQ cluster. When it receives a content invalidation message from our[ API](https://docs.transparentedge.eu/v/english/getting-started/faq/glosario/api), the message is immediately consumed by an agent which runs on all our CDN nodes. The agent locally invalidates the requested content at that node. If you want to find out more about how to invalidate content, click this[ link](https://docs.transparentedge.eu/getting-started/dashboard/invalidando-contenido). --- # Agent Instructions: 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: ``` GET https://docs.transparentedge.eu/getting-started/faq/features/fast-purging.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
