Failover protection
Failover protection is available on the following networks for customers on the Growth or Custom plans:
The failover protection feature ensures API requests are fulfilled even if Infura experiences a service issue or outage. This is achieved by routing requests to a select partner.
Failover protection is enabled on a per-request basis by adding the failover header to your API request (see Enable API request forwarding). This gives you control over which requests you'd like fulfilled by Infura's partner if failover protection should be needed.
