Cloudflare encountered issues this morning, which caused widespread disruption to online services and platforms.
Cloudflare is one of the leading Content Delivery Networks (CDNs) today. The American company also provides Distributed Denial of Service (DoS) protection to online domains, speed optimization, and various cybersecurity services.
The company has millions of customers worldwide, including large corporations.
On Tuesday morning, a number of websites and online services suddenly went down, including Feedly, Cloudflare itself, blogs, cryptocurrency services, and more. Ironically, outage monitors – websites used to check the status of another domain you’re having trouble connecting to – were also affected by the outage.
Given the reach and scale of Cloudflare, when the company’s network goes down, the entire internet suffers the consequences.
In an update at 06:43 UTC, Cloudflare’s service team said it was investigating “widespread issues with its services and/or network.”
The company said, “Users may experience errors or delays in reaching Cloudflare’s network or services. We will update this status page to clarify the scope of the impact as we go along. as we continue the investigation.”
Problem solved in less than two hours
In another update about 30 minutes later, Cloudflare said: “The issue has been identified and a fix is being implemented.”
Cloudflare described the situation as a “critical P0” incident – a situation described as an urgent, first priority issue. Additionally, the company said the incident impacted Cloudflare’s network connectivity in “wide regions,” resulting in 500 errors.
At 7:20 UTC, Cloudflare said a first patch had been deployed. It appears that service has been restored for some websites and online platforms that were taken offline by the issue on Cloudflare’s network.
At 08:06 UTC, Cloudflare’s update page indicated that all services were now up and running.
Contacted by ZDNet, Cloudflare said:
“Earlier today, Cloudflare experienced an outage in parts of our network. This was not the result of an attack. A network configuration change in some of our data centers resulted in the unavailability of part of our network.
Due to the nature of the incident, customers may have had difficulty accessing websites and services that rely on Cloudflare between approximately 6:28 a.m. and 7:20 a.m. UTC. Cloudflare worked on a solution within minutes, and the network is now functioning normally.”
It’s not exactly a first. In 2019, Cloudflare had already encountered an outage that affected numerous customer services for the American company’s solutions. In the same vein, the outage that affected CDN Fastly in 2021 also had repercussions for several online services and websites. Cloudflare is now among the top three most used companies for CDN services, alongside Akamai and Amazon Cloudfront.
