We have chosen to use solutions from different providers for Product Reference Data (PRD) and Consumer Data.
The Consumer Data Standards require Data Holders (DH) to host two endpoints, Get Status and Get Outages. Are you able to provide some guidance on which vendor should be responsible for the endpoints, assuming only one can do this? Would we need to manage both vendors to adhere to the availability requirements?
The Get Status and Get Outages APIs are intended to represent your CDR implementation as a whole. If there is an outage in either PRD or Authenticated APIs then the outage and status API responses should reflect this.
As long as you meet this obligation you comply with the standards. It is up to each DH to choose how to do this. In your case you could ask vendor A, vendor B, a combination of A and B or even a third vendor C to publish these APIs.
