I think it looks fine my way, but I don't mind doing it your way either so I've updated it.

I don't love that this exception isn't defined in an exceptions module, but perhaps it's overkill if app.exceptions doesn't already exist?

Support fallbacking from replicas that go down and support multiple replica options. See this ticket's comment for full details.
How did you test this code?
I hard coded a single default database. Extensive testing by hand to make sure the caches and connections worked, then later I introduced one test that verifies the connection works against the default database and in addition to that I added in several tests against the router logic with mocked logic to mimic database connection issues.
