Building a resilient solution

If you implemented Episerver Search & Navigation (formerly Episerver Find) in your solution, this topic suggests way to keep your site working, should the service become available.

Search & Navigation reliability

You should count on the reliability specified in your service level agreement (SLA). Nevertheless, as search and navigation is a central part of a solution, you should implement a graceful degradation strategy if the Search & Navigation service should become unavailable.

Note: If Episerver is not hosting Search & Navigation, Episerver cannot guarantee the connection between an application and the Search & Navigation service.
