D1community-d1-557m-writes

557 million D1 rows written produced about $949.

Community user s0565184740 says their first-ever usage invoice, about $949, was driven almost entirely by 557 million D1 rows written from a now-fixed code bug, and that the account was restricted with "Exceeded maximum DB size" on every D1 write. They ask for a goodwill waiver and service restoration but say the Support Portal offered no way to open a billing case; an MVP replied that opening all the questions reveals the button.

Durable Objects

Lion Brain: a Durable Object alarm loop from an AI-coding bug wrote about 250 million rows, roughly $210.

Replying in another user's Community thread, bennygoldstein says a bug written by an AI coding tool made a Durable Object alarm in their Lion Brain app re-index the same data every few seconds on October 10 and 11, 2026, writing about 250 million rows and costing roughly $210 in overage on Workers Paid. He says he only found out from the budget alert email, which never pauses anything, and that he opened a billing case asking for a one-time courtesy credit and a real hard spending cap.
