You can use high availability and read replicas on your Timescale services to significantly reduce the risk of downtime and data loss due to failures, and to more effectively scale the limits of your service.

HA replicas in Timescale are exact, up-to-date copies of your database that automatically take over operations if your primary becomes unavailable, including during maintenance.

Read replicas can create an isolated environment to run heavy analytical queries, so that you don't need to run them on a production instance, and risk impacting performance.

If you are using Managed Service for TimescaleDB, see the Managed Service for TimescaleDB failover section.

If you are using self-hosted TimescaleDB, see the self-hosted HA section.
