Approval gate for databases runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 13 Nov 2026.

Nothing serious here today
Today is the operative word: we check Approval gate for databases every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
