UPD. Cloudflare said the issue was resolved. The company attributed the outage to an "unusual" spike in traffic.
Today, November 18, there was a massive outage at Cloudflare, one of the world's largest CDN and cloud security companies. This caused disruptions in the work of Internet services and websites around the world, including in Ukraine. The company's shares fell due to the fact that among the victims were such tech giants as X, Amazon, OpenAI and others. Cloudflare talks about a surge in unusual traffic, but does not yet know the reason.
Today, November 18, there was a massive outage at Cloudflare, one of the world's largest CDN and cloud security companies. This caused disruptions in the work of Internet services and websites around the world, including in Ukraine. The company's shares fell due to the fact that among the victims were such tech giants as X, Amazon, OpenAI and others. Cloudflare talks about a surge in unusual traffic, but does not yet know the reason.
What is known about the incident?
According to DownDetector, reports of a global outage at Cloudflare began appearing at approximately 1:00 p.m. Kyiv time.
At 1:48 p.m. Kyiv time, Cloudflare reported a problem, including widespread 500 errors, as well as crashes in the Cloudflare dashboard and API. The company said it was investigating the issue.
"We are seeing services being restored, but customers may continue to see higher than usual error rates as we continue our troubleshooting efforts," the company said in a statement.
But 15 minutes later, a message appeared again stating that the issue was being investigated. The company then said that while it was trying to fix the situation in London, it was disabling access to WARP, a tool from Cloudflare that functions as a modern VPN service that increases internet connection speed and protects traffic from ISPs or hackers.
The outage has already affected X, Spotify, Amazon, OpenAI, PayPal, Uber, and others. Against this backdrop, the company's shares have already fallen by 3.9%.
It's unclear what caused the issue, but Cloudflare said it would be conducting scheduled maintenance on its data center in Santiago today.
“We have applied the fix and believe the outage has been fully resolved. However, we continue to monitor the error to ensure full restoration of all services,” the company’s website says.
What the company says about the failure
A Cloudflare spokesperson told The Guardian: “We have seen a spike in unusual traffic to one of our Cloudflare services starting at 11:20am UTC. This caused some traffic to fail across the Cloudflare network. While most traffic for most services continued to flow normally, we have seen an increase in errors across a few Cloudflare services.”
"We do not yet know the reason for the unusual traffic spike. We are all making every effort to ensure that all traffic is being served without errors. After that, we will turn our attention to investigating the cause of the unusual traffic spike," the company spokesperson added.
