Multiple Online Services Disrupted by Cloudflare Glitch
Numerous platforms, including LinkedIn, Zoom, and Downdetector, experienced disruptions on Friday due to renewed technical issues at Cloudflare—marking the company’s second service interruption in under a month.
Cloudflare attributed the outage to an adjustment in its firewall, implemented in response to a recently disclosed software vulnerability. The company clarified that the incident was not the result of an attack. Separate concerns had also been raised regarding its application programming interfaces earlier that day.
The problem lasted approximately 30 minutes and was resolved shortly after 9 a.m. GMT. This follows a more extensive disruption in mid-November, which impacted platforms including X, OpenAI, Spotify, and multiplayer games like League of Legends. That earlier outage stemmed from an oversized configuration file designed to manage malicious traffic, leading to a system crash.
Friday’s disruption appeared less severe, though it still affected sites such as Canva, Shopify, India-based broker Groww, and Downdetector—a platform tracking online service issues. Upon returning online, Downdetector recorded over 4,500 reports linked to Cloudflare.
Given recent high-profile internet outages, some businesses may reassess their reliance on Cloudflare’s infrastructure.
Steven Murdoch, a computer science professor at University College London, noted: “Two outages in quick succession will likely raise concerns. While Cloudflare expresses regret, it remains unclear whether this reflects systemic flaws or isolated incidents.”
He added that Cloudflare, a global provider of cloud and cybersecurity solutions, positions reliability as a cornerstone of its services. Organizations rely on it for enhanced performance and protection against specific cyber threats.
Recent disruptions at Cloudflare, alongside an Amazon Web Services outage in October affecting over 2,000 companies globally, have reignited debates among experts about the risks of centralizing critical internet infrastructure.
“Centralization is extensive,” Murdoch observed. “Cloudflare’s popularity is driven by quality, but this concentration creates vulnerabilities.”
Michał “rysiek” Woźniak, an internet infrastructure specialist, commented: “This highlights the fragility of major tech-dependent systems. Since October 20, this marks the fourth significant global outage noticeable to mainstream audiences and ordinary users.”
Cloudflare states that roughly 20% of websites utilize its services in some capacity. With nearly 300,000 clients across 125 countries, it reports thwarting billions of cyber threats daily.
