A Post Mortem on this Morning's Incident

This post details two incidents of significant packet loss on a major transit provider (Telia Carrier) in June 2016. It highlights the impact on Cloudflare customers (522 errors) and outlines Cloudflare's response, including taking down ports with the problematic provider and shifting traffic. Crucially, it discusses the need for improved communication during incidents and the ongoing work to build a more resilient network through greater interconnection, automated mitigation systems (augmenting BGP to detect packet loss), and increased failover capacity. The post announces plans to extend automated detection and mitigation capabilities to all POPs.
