USPS tracking should be using an indexed id (you don't want to allow partial matches/searches here), so I'd expect even very modest hardware to handle 10s of thousands of requests per second. Likewise with things like CRUD forms. Right now your link shows only ~5700 requests in the last 30 minutes for GSA advantage, or ~3/s. Sex offender registry has ~3500/30m or 2/s. Even USPS tracking is only at ~12k/30m or ~7/s. It's still only 9am on the west coast so maybe they need to handle 100000x traffic for peaks, but I doubt it.
