Cloudflare Outage Disrupts Internet Worldwide
Cloudflare Outage Disrupts Internet Worldwide
The News
Internet infrastructure company Cloudflare was hit by an outage on Tuesday, knocking several major websites offline for global users.
E-commerce platform Shopify, job search engine Indeed, Anthropic’s Claude chatbot, President Donald Trump’s Truth Social and Elon Musk’s social media platform X were among the sites impacted by the Cloudflare issues, according to Downdetector, which itself could not be accessed briefly for some users. Some of NJ Transit’s digital services were brought down by the outage.
OpenAI’s status page indicated ChatGPT and its Sora short-form video app had fully recovered after they experienced issues due to a “third-party service provider.”
A Cloudflare spokesperson said the “root cause” of the outage was an automatically generated configuration file used to manage threat traffic that “grew beyond an expected size of entries,” which triggered a crash in the software system that handles traffic for several of its services.
Timeline
Many sites came back online within a few hours. In an update to its status page around 9:57 a.m. ET, Cloudflare said it had implemented a fix to resolve the outage, though it noted some users may still experience issues accessing its online dashboard.
The company said it began to observe a “spike in unusual traffic” around 5:20 a.m. ET.
Reactions
“We are continuing to monitor for errors to ensure all services are back to normal,” the company added.
There’s no evidence that the outage was a result of an attack or caused by malicious activity, the spokesperson added.
“Given the importance of Cloudflare’s services, any outage is unacceptable,” the spokesperson said. “We apologize to our customers and the internet in general for letting you down today.”
More
Cloudflare’s software is used by many businesses worldwide, helping to manage and secure traffic for about 20% of the web. Among the services it provides are that it guards against distributed denial of service attacks, which are when malicious actors attempt to overload a website’s system with so many traffic requests that it can’t function.
Shares of Cloudflare slid more than 2%.
The issue comes less than a month after Amazon Web Services suffered a daylong disruption that took down numerous online services, followed by a global outage of Microsoft’s Azure cloud and 365 services.
In July 2024, a faulty software upgrade by cybersecurity firm CrowdStrike caused a widespread outage that temporarily halted flights, impacted financial services and pushed hospitals to delay procedures.
