A significant disruption to Cloudflare’s global network services has triggered widespread connectivity problems, leaving users across the globe facing “internal server error” messages when trying to reach numerous websites and online platforms. The company confirmed it is actively investigating the incident, which has impacted a substantial portion of its infrastructure.
Cloudflare operates a massive distributed network comprising servers and data centers in more than 330 cities spanning over 120 countries. This infrastructure is fundamental to providing content delivery, security, and performance optimization for a vast array of internet services. The network boasts an impressive 449 Tbps global network edge capacity and maintains interconnections with over 13,000 networks worldwide, including every major internet service provider, cloud platform, and large enterprise.
The internet infrastructure firm first acknowledged technical difficulties roughly forty minutes before escalating its alerts. Initially, the company reported availability issues with its own support portal. Shortly after, at 11:48 UTC, a new incident report was issued, notifying customers that the broader Cloudflare Global Network was experiencing significant problems. In an official statement, Cloudflare said, “Cloudflare is aware of, and investigating an issue which impacts multiple customers: Widespread 500 errors, Cloudflare Dashboard and API also failing. We are working to understand the full impact and mitigate this problem. More updates to follow shortly.”
While the full scope of the outage was not immediately detailed by Cloudflare, independent tests revealed that numerous Cloudflare nodes throughout Europe were non-operational. Affected locations included major hubs such as Bucharest, Zurich, Warsaw, Oslo, Amsterdam, Berlin, Frankfurt, Vienna, Stockholm, and Hamburg. Concurrently, the outage tracking service Downdetector registered a sharp spike in user reports, tallying tens of thousands of complaints related to server connection failures, website inaccessibility, and hosting problems.
Although a direct link to the Cloudflare incident was not confirmed, Downdetector also showed hundreds of thousands of additional reports from users struggling to connect to various popular online services. Platforms like Spotify, Twitter, OpenAI, League of Legends, Valorant, AWS, and Google were among those noted by users as experiencing difficulties. This is not the first time Cloudflare has faced such a challenge; the company addressed another major outage in June that caused Zero Trust WARP connectivity and Access authentication failures across multiple regions, an event that also impacted Google Cloud infrastructure.
In a related context, Amazon confronted a severe outage in October stemming from a significant DNS failure that disrupted connectivity to millions of websites and platforms hosted on its Amazon Web Services (AWS) cloud computing platform.
Update November 18, 12:21 UTC: Cloudflare began observing initial signs of network recovery. The company stated, “We are seeing services recover, but customers may continue to observe higher-than-normal error rates as we continue remediation efforts.”
Update November 18, 13:13 UTC: A subsequent update confirmed that some services had been successfully restored while work continued on others. “We have made changes that have allowed Cloudflare Access and WARP to recover. Error levels for Access and WARP users have returned to pre-incident rates. We have re-enabled WARP access in London. We are continuing working on restoring service for application services customers.”
Update November 18, 17:44 UTC: Approximately six hours after the outage began, Cloudflare announced that all issues had been fully resolved. The company confirmed, “Cloudflare services are currently operating normally. We are no longer observing elevated errors or latency across the network. Our engineering teams continue to closely monitor the platform and perform a deeper investigation into the earlier disruption, but no configuration changes are being made at this time.”
