Cloudflare says CenturyLink is to blame for the outage that occurred overnight

An example of why you don't want to put all of your "internet eggs" in one basket.

What’s the skinny? A rather large network outage lasting several hours occurred overnight last night. In an email sent out to it’s customers, Cloudflare stated that: “at approximately 10:03 UTC, a misconfiguration at a major external network provider caused connectivity disruptions across the Internet. These disruptions impacted the operations of many service providers, including Cloudflare.”

Thanks to their automated system only a few minutes went by before the system automatically rerouted traffic away from CenturyLink. Still however some customers continued to see issues which Cloudflare attributes to CenturyLink being so large. “CenturyLink/Level(3) is among the largest network providers in the world. As a result, many hosting providers only have single-homed connectivity to the Internet through their network.”

The graph below displays the six major tier-1 networks Cloudlfare connects to and shows CenturyLink in red dropping to near-zero during the incident.

The outage lasted approximately four and a half hours and Cloudflare says they’re still awaiting a postmortem from CenturyLink. The email I received from Cloudflare however suggested that a misconfiguration on CenturyLinks end is to blame. I suppose that’s just a blanket statement they’re using as they await news of the real “cause of death”.
