I can see a fairly simple improvement to updating the entire HIBP dataset; version it and slowly roll traffic onto the new version by prefix, e.g. take the 6-hexit prefix mod 100 and if the result is < rollout_percentage then the cloud flare workers fetch from the new version, otherwise the old. Rollout_percentage can be a simple function of Unix timestamp for example.
