Overpass API has become the most used database to extract OSM data over the web. Yet it remained highly available. This high availability of Overpass API is ensured by its load management. For the first part of the talk we will discuss statistics for the historic and current usage of Overpass API. In the second part, we will present the mechanisms used for this load management and explain how to assess the footprint of a query. Finally we will advise how to get response to your queries as fast as possible.
