Cloudflare is back in the spotlight after a new wave of outages that, on December 5, 2025, is affecting several components of the platform.
In addition to the Dashboard and API issues already reported by users around the world, the company confirmed that it is also working on a significant increase in errors related to Cloudflare Workers , the serverless service used by thousands of developers to automate critical functions of their applications.
Another piece that adds to a mosaic of significant critical issues.
As numerous cybersecurity experts have been pointing out for years, entrusting the web’s core infrastructure to a handful of companies creates structural bottlenecks. And when one of these nodes fails— as happened with Cloudflare —the entire ecosystem suffers.
A glitch can block automations, custom APIs, logical redirects, authentication functions, and even built-in security systems. A single glitch can trigger a domino effect far beyond what was anticipated.
Further complicating the situation, scheduled maintenance is also underway today at the DTW datacenter in Detroit , potentially resulting in traffic rerouting and increased latency for users in the area. While this maintenance is planned and managed, the combination of Workers and Dashboard issues increases the level of uncertainty. In some specific cases—such as for PNI/CNI customers connecting directly to the datacenter—certain network interfaces may be temporarily unavailable, causing forced failovers to alternative paths.
The crux of the matter remains the same: this centralization exposes the web to enormous operational and security risks . When a platform like Cloudflare fails, even for just a few hours, DDoS protections, anti-bot systems, and firewall rules are weakened, creating windows of vulnerability that even the most sophisticated attackers could attempt to exploit.
The dependence on a single giant for such delicate functions is a point of fragility that can no longer be ignored.
The previous global blackout— documented with great transparency by Cloudflare itself and analyzed by Red Hot Cyber—had highlighted how an internal error in the backbone configuration could take significant portions of the world’s traffic offline.
Today we are not (yet) faced with a failure of this magnitude, but the sum of multiple simultaneous outages brings to mind that case and raises doubts about the overall resilience of the infrastructure.
Cloudflare’s latest downtime, this time spread across multiple layers of the platform, demonstrates how fragile the modern internet is and how much its reliability depends on a few key players. Companies —small or large— that build their services on this foundation should start seriously considering multi-provider redundancy plans. Because when a single point goes down, half the web risks going down.
