Cloudflare suffered an outage that affected traffic in 19 of our data centers. Unfortunately, these 19 locations handle a significant proportion of our global traffic. This outage was caused by a change that was part of a long-running project to increase resilience in our busiest locations. A change to the network configuration in those locations caused an outage which started at 06:27 UTC. At 06:58 UTC the first data center was brought back online and by 07:42 UTC all data centers were online and working correctly.
Depending on your location in the world you may have been unable to access websites and services that rely on Cloudflare. In other locations, Cloudflare continued to operate normally.
We are very sorry for this outage. This was our error and not the result of an attack or malicious activity.
