Thus if one setup fails, API user’s OS will automatically try to hit other setup in different and user will get very high availability.
The above arrangement fails at times when application on any of the region cluster is still responding but link to NIC or some other thing goes wrong and user has no option to manually try hitting the other working setup.
Thus, we suggest ASPs to give options of choosing particular server temporarily (and keeping user educated to primarily use Main Base URL and only using the URL which targets single region only as Remedy…)
