On November 14th, a Logpush update caused a significant error. Cloudflare’s incident report revealed that the update did not direct auxiliary tools to send the collected logs. Consequently, the logs were collected but never delivered and were eventually lost when the cache was cleared.
“A misconfiguration in one part of the system caused a cascading overload in another part of the system, which was itself misconfigured. Had it been properly configured, it could have prevented the loss of logs,” Cloudflare stated in their report.
Engineers team quickly found the flaw and reverted the update, but this caused a cascading failure. The system became overwhelmed with excessive log data, including from users who hadn’t set up Logpush, worsening the problem.
Cloudflare has apologized for the loss of user data and is implementing measures to prevent future incidents, though efforts are still underway.
The loss of important log data highlights the need for thorough testing and backup measures to maintain the integrity and availability of crucial information.
