It should be mentioned that I operate one of the only remaining Testnet v3 faucets as well.  Even with the sudden rush of users, I think we've only had our faucet go dry for a few days at a time.  Mostly to take a few days and just attempt to shake off the abusers.

My organization has been giving away Bitcoin Testnet since 2022.
