Coinbase CEO Brian Armstrong posted on the X platform that there was a service outage at Coinbase yesterday, which is absolutely unacceptable. The root cause was multiple cooling units at the AWS data center failing simultaneously, leading to overheating in one server room. Most of Coinbase's systems are designed with redundancy to handle the failure of a single availability zone, and they did operate normally last night.However, centralized exchanges were not spared, as their architecture is specially optimized for low latency and customer co-location, making it difficult to simultaneously ensure fault tolerance at the availability zone level. While enabling the exchange to withstand availability zone failures would introduce latency issues and disrupt customer co-location, the team will reassess these trade-offs to at least ensure that when a switch to a different availability zone is needed, the duration of the outage can be significantly reduced. He expressed gratitude to the AWS and Coinbase teams who worked through the night to repair the issue and promised to release a detailed technical explanation later.

The Coinbase exchange has been down for over 2 hours, and its status page redirects users to the AWS status page.

According to an analysis report published by Cloudflare's official blog, the large-scale outage on November 18 was not caused by an external network attack, but rather by an erroneous configuration file generated after a database permission adjustment, which led to anomalies in the core proxy system. This triggered interruptions in multiple products, including CDN, security services, Workers KV, Turnstile, and Access, marking the most severe incident since 2019.The report noted that in the early stages of the incident, the team mistakenly assessed it as a DDoS attack, and ultimately completed the fix by rolling back to an old configuration file. The related services were fully restored at 01:06 AM Beijing time on November 19. Cloudflare described this outage as "unacceptable" and will accelerate the improvement of system resilience.
