Community user markbooth63, a solo developer on Pages and D1, says a coding bug ran a full table scan on every API request on April 7, 2026, causing 6.3 trillion D1 row reads in a few hours and a $6,781 invoice. He says he fixed it and filed a billing dispute the same day, added an index, and that after 10 days without a response the balance was reduced to $6,357 with no explanation.
