Area:
Many solutions depend heavily on functionality like search-based landing pages. This topic suggests ways to keep your site working, should the Episerver Search & Navigation (formerly Episerver Find) service become unavailable.
Service reliability
You should count on the reliability specified in your service level agreement (SLA). Nevertheless, as search 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.
Recommendations for coping with downtime
Leave the search-generated page sections blank
For example, a page displays a list of most watched products, which is fetched from Search & Navigation. If Search & Navigation is down, display a blank list.
