A Cloudflare engineer decided to apply a throttling mechanism to prevent the zone from pulling so much traffic from their origin. Let's be very clear on this action: Cloudflare does not have an established process to throttle customers that consume large amounts of bandwidth, and does not intend to have one. This remediation was a mistake, it was not sanctioned, and we deeply regret it.
