# Open subscriptions

Liberator supports open subscriptions. That is, it can keep a user’s [subscription request](../datasource/datasource-subscriptions.md) open even if the DataSource peer that can satisfy the request is down when the request is made. The request is completed once the DataSource peer is available.
