Cloudflare incident on November 14, 2024, resulting in lost logs

On November 14, 2024, Cloudflare experienced a Cloudflare Logs outage, impacting the majority of customers using these products. During the ~3.5 hours that these services were impacted, about 55% of the logs we normally send to customers were not sent and were lost. The details of what went wrong and why are interesting both for customers and practitioners.
