Cloudflare Outage Wreaks Havoc on Major Sites Around the World [Updated]

Cloudflare, a company that provides CDN services to major websites around the world, recently experienced an outage that took down many of their customers’ sites.

The outage began around 7AM EST, and many major companies, including web hosting company WP Engine and chat service Discord also experienced outages due to issues over at Cloudflare.

Cloudflare has identified the source of the problem and implemented a temporary fix until the issues can be resolved permanently.

Current Status

According to the Cloudflare status page, all systems are now operational. The outage was due to a route leak. Route leaks are a type of attack where web hosting providers leave paths unprotected that allow access to block IP addresses.

In this case, though, a piece of equipment called a BGP optimizer at a small company in Pennsylvania was the source of the problem. The BGP optimizer created inaccurate paths for internet traffic to travel to Cloudflare sites. These paths were broadcasted through the web host. That’s why so many sites were unavailable. The web hosting provider, Verizon, didn’t have any monitoring in place to catch this problem. Luckily, the folks at Cloudflare quickly detected the problem and were able to get it fixed.

Twitter is Abuzz With the News

As usual, Cloudflare users have taken to Twitter to express their frustration with the outage. Many have stated “half the internet is down.”

Webmasters that rely on Cloudflare for hosting, caching and other services scrambled to find a way to bring their websites back online.
