# Disaster recovery **(FREE SELF)**
This document describes a feature that allows you to disable some important but computationally
expensive parts of the application to relieve stress on the database during an ongoing downtime.
## `ci_queueing_disaster_recovery`
This feature flag, if temporarily enabled, disables fair scheduling on shared runners.
This can help to reduce system resource usage on the `jobs/request` endpoint
by significantly reducing the computations being performed.
Side effects:
- In case of a large backlog of jobs, the jobs are processed in the order
they were put in the system, instead of balancing the jobs across many projects.
- Projects which are out of quota will be run. This affects
only jobs created during the last hour, as prior jobs are canceled
by a periodic background worker (`StuckCiJobsWorker`).
