Introduction: When the Internet Stumbles

A significant portion of the internet ground to a halt on Tuesday, November 18, 2025, as a major Cloudflare outage caused widespread disruptions. For businesses and individuals relying on seamless internet access, the event was a stark reminder of the web's interconnectedness and the critical role of resilient online tools, including reliable proxies.

The outage, which began to surface in the early hours, left users unable to access a multitude of popular websites and online services. Reports of the internet outage flooded social media as users encountered "500 Internal Server Error" messages on platforms ranging from social media giants and communication tools to gaming services and AI applications. This widespread Cloudflare down event highlights a crucial vulnerability in modern digital infrastructure.

What Caused the Widespread Disruption?

Cloudflare's Chief Technology Officer, Dane Knecht, explained that the outage was not the result of a malicious attack. Instead, it was triggered by a "latent bug in a service underpinning our bot mitigation capability" that was activated by a routine configuration change. This initial glitch created a domino effect, leading to a "broad degradation" across their network and services. The incident highlights the complexity of the internet's backbone, where a minor internal issue can have a significant global impact on internet resilience.

The company confirmed it was an "internal service degradation" and that their dashboard and API were also failing. The issue was eventually resolved, with Cloudflare implementing a fix and monitoring the situation to restore normal service.

The Ripple Effect: How a Cloudflare Outage Interrupts Proxy Services

For users of proxy services, a Cloudflare outage can manifest in several frustrating ways, causing significant proxy interruption. Since Cloudflare acts as a reverse proxy for a vast number of websites, its downtime means that any attempt to connect to a Cloudflare-protected site through a proxy will fail. This is because the proxy's request cannot reach the intended destination if the intermediary, in this case, Cloudflare, is down. The key search query here is: what happens to proxies when Cloudflare is down?

Furthermore, a critical aspect of Cloudflare's service is its security features, which include Cloudflare bot mitigation and challenges to verify that a user is human. During the recent outage, services like "challenges.cloudflare.com" were inaccessible, meaning any proxy user attempting to access a site that requires such a verification would be blocked.

This is where the type of proxy you use becomes paramount for avoiding proxy blocks and ensuring business continuity.

Why Your Choice of Proxy Matters During a CDN Outage

While a widespread CDN outage like Cloudflare's can impact all internet traffic, not all proxies are affected equally. The key differentiator lies in the IP address reputation.

Datacenter Proxies

Datacenter Proxies are often the first to be flagged by services like Cloudflare, even under normal circumstances. Their IP addresses are easily identifiable as originating from data centers, which can trigger heightened security scrutiny and lead to blocks. During an outage where security systems may be partially active or behaving erratically, datacenter proxies are likely to face significant connectivity issues.

Residential Proxies

In contrast, Residential Proxies, such as those offered by Novaproxy.io, utilize IP addresses assigned by Internet Service Providers (ISPs) to homeowners. This makes them appear as genuine, everyday users to websites and security systems. Consequently, they are far less likely to be automatically blocked. During a Cloudflare outage, while access to protected sites would still be impossible due to the site being offline, residential proxies are better positioned to resume normal operations once the target site is back online, without the added hurdle of being flagged as suspicious. They are often considered the best proxy for web scraping due to their high success rates.

Mobile and Static ISP Proxies: A Step Ahead in Reliability

The principle of IP reputation extends to mobile and static ISP proxies, making them robust choices for uninterrupted access.

Mobile Proxies: These proxies use IP addresses from mobile carriers. The dynamic nature of mobile networks and the fact that a single IP can be shared by many users make them highly resilient to blocking. Their legitimacy is high, ensuring smoother connections.
Static ISP Proxies: Offering a dedicated residential IP from an ISP, these proxies combine the high trust factor of a residential connection with the stability of a static IP. This makes them an excellent choice for consistent and reliable access to a wide range of online resources.
