This flipper exists so that if there are problems with the Provider Profile Management System (PPMS) we have the ability to disable all the front-end search interfaces that rely (either fully or partially) on data from PPMS. At this time, the following Facility locator searches rely on data from PPMS:

• Facility Type = Community providers (in VA’s network)
• Facility Type = Community pharmacies (in VA’s network)
• Facility Type = Urgent care + Service type = All in-network urgent care
• Facility Type = Urgent care + Service type - In-network community urgent care
• Facility Type = Emergency care + Service type = All in-network emergency care
• Facility Type = Emergency care + Service type - In-network community emergency care

@jilladams @FranECross @mmiddaugh This flipper audit was done in late 2022. Would it even still be accurate? Are we realistically going to chase this work at any point?

I don't know how to answer. Does the Platform definitely want us to be removing unused Flippers due to performance overhead on the VA.gov site? Yep. Will we ever choose to prioritize this work? ...I'm not sure. Can we walk away from the tech debt just because we don't intend to prioritize it? ...dunno. If the Platform ever got worked up about Flipper performance again, and put pressure on teams to remove their old flippers: we would definitely have to prioritize this work and the other tickets like it. 🤷‍♀️

Makes sense. Backlog seems like a good place for it for now.
