Given the relatively slim page size (23Kb for me), and given that SQLite can pretty easily host a relatively simple database like this one and serve 100K-1M queries per day[0], I would expect that whoever is hosting this could pretty easily host this on a single dedicated server which only costs ~$50. So for the foreseeable future, I suspect this site will be fine.
