babynarc: a Durable Objects alarm loop and a surprise bill that grew from $300 to $500.
@babynarc says an alarm loop in an old Durable Object he thought was inactive left him badly burned: he watched a surprise $300 bill grow to $500 even after killing it. Replying to Cloudflare's Dane Knecht and Kenton Varda, he suggests prepending budget-alert details to every `cf` result by default.

@shmily7 reports a Durable Object alarm loop in an unused test project, then says he paid the full US$10,811.41 bill to avoid service suspension. Cloudflare’s Ashley Peacock publicly says he is looking into it internally and will follow up. Cloudflare’s Dane Knecht later replies that he escalated it too. On October 9 the author declares the case closed: he reports that, with Ashley Peacock’s help, Cloudflare decided to refund the charges incurred during the bug in full, with the money still to arrive, and posts the support ticket reply he received.

Paweł Mioduszewski: an R2-event queue loop, a $302 charge and a reported $284 account credit.
Paweł Mioduszewski (@mioduszewsky) says buggy Worker code created an infinite loop on an "R2-object-created" queue, with the consumer saving files back into the same bucket. He first estimated at least $343 across Workers, Image Transformations and Queues, then says Cloudflare charged him $302 while his support case waited. About three weeks after contacting support, he reports no cash refund but a $284 account credit that basically wiped the Image Transformations charges.
