Cloudflare Experiences Brief Outage, Affecting Global Websites
Cloudflare faced a short outage on Friday that took numerous websites offline worldwide. This incident follows another significant outage just weeks prior that disrupted large parts of the internet.
According to reports, issues with Cloudflare led to a notable number of websites becoming inaccessible, including platforms like LinkedIn, Coinbase, Substack, Shopify, HSBC, and Deliveroo. The outage monitoring site Downdetector reported a surge in user complaints about website access during the early hours on the East Coast, indicating the widespread impact of the situation.
Cloudflare promptly recognized the problem and stated that it was looking into the cause. Following the news of many websites being down, the company’s stock dipped by as much as 4.5% in pre-market trading. However, just a few minutes later, Cloudflare reported that it had “implemented the fix” and was monitoring the outcomes. This swift action helped mitigate the effects, allowing many affected sites to come back online shortly after. As a result, Cloudflare’s stock regained some losses, trading less than 2% lower by mid-morning.
This latest incident comes on the heels of a previous outage that crippled major parts of the internet less than three weeks ago.
In a recently published blog post, Cloudflare clarified that the outage stemmed from an internal programming mishap. They emphasized that “this issue was not caused, directly or indirectly, by any type of cyber-attack or malicious activity.” The problem originated from changes made to permissions in the database connected to their bot management system, resulting in the creation of an unexpectedly large configuration file. This large file, when propagated through Cloudflare’s network, exceeded software limitations, causing significant failures in their core traffic management systems.
Cloudflare’s technology is crucial for thousands of companies globally, managing and securing about 20 percent of internet traffic. One of its essential roles is to shield clients from distributed denial of service (DDoS) attacks, where attackers flood a website with excessive traffic, hindering its functionality. Interestingly, for the second time in a short span, a Cloudflare outage, rather than a malicious attack, led to the disabling of a client’s website.
