Cloudflare Outage Shuts Down Global Services Like ChatGPT and X

-

Major Internet Outage Caused by Cloudflare

A significant network outage caused by Cloudflare, a leading cloud infrastructure company, has disrupted multiple online services, including ChatGPT and X (formerly Twitter). The incident began at 8:48 p.m. on the 18th, as reported by Cloudflare, due to performance degradation in its internal services.

According to a representative from Cloudflare who spoke with Bloomberg News, "We detected a sudden surge in abnormal traffic to one of our services," which led to errors in some traffic passing through the Cloudflare network. This disruption affected a wide range of online platforms and services, highlighting the critical role that Cloudflare plays in managing internet traffic.

Cloudflare functions as a server optimization service provider, helping users access websites quickly and securely. While cloud platforms like Amazon Web Services (AWS) or Microsoft Azure provide foundational infrastructure such as servers and databases, Cloudflare is responsible for regulating server traffic, blocking hacking attempts, and delivering content rapidly to users. Given that approximately one-fifth of global internet traffic passes through Cloudflare’s network, any issues within its system can lead to large-scale disruptions.

Impact on Various Online Services

DownDetector, a service that monitors website outages, noted around 8:30 p.m. that "reports of disruptions surged across most sites, including Cloudflare." Affected services included OpenAI’s ChatGPT, X, Google, YouTube, Facebook, Amazon, the online game League of Legends, cloud services AWS and Microsoft Azure, cryptocurrency exchange Coinbase, Moody’s credit rating service, and some digital services of the New Jersey Department of Transportation, which were halted or delayed.

The outage lasted for about three hours before Cloudflare announced around 11:42 p.m. that "the incident is now resolved." However, foreign media reported that the cause of the disruption remains under investigation.

Increasing Frequency of Cloud Service Disruptions

Recent disruptions in cloud services have become increasingly frequent, often causing global app and website outages. As numerous businesses and services rely on specific cloud and AI infrastructures, even minor failures or errors can now lead to larger-scale damage.

For example, last month, an outage in AWS’s 'US East 1 Region' in Virginia caused errors in global corporate and public services. The same month, an Azure outage paralyzed major services and apps worldwide. These incidents underscore the growing dependency on cloud infrastructure and the potential consequences of even brief disruptions.

Conclusion

The recent Cloudflare outage serves as a reminder of the interconnected nature of today's digital ecosystem. With so many critical services relying on cloud infrastructure, ensuring the reliability and resilience of these systems is more important than ever. As companies continue to depend on cloud services for their operations, the need for robust and secure infrastructure becomes paramount. The ongoing investigations into the cause of this outage will be crucial in preventing similar incidents in the future.

The Rise of AI-Powered Real Estate Discovery in Japan In Tokyo, a growing number of Japanese companies are leveraging satellite imagery and artificial intelligence to identify abandoned houses that could be repurposed or sold. This innovative approach is becoming increasingly vital as the country faces a rising number of deserted properties due to its aging population. Where Inc., a startup, offers a service that uses AI trained on tens of thousands of images to detect signs of aging roofs, such as rust and discoloration. These findings are then overlaid on satellite maps, helping users spot properties that may have been left unattended. One of Where Inc.'s users, Kotaro Yasue, recently discovered a two-story wooden house through this service. He was able to contact the owner via a real estate registry. It turned out that the house had been neglected for over a decade, and the owner was unsure how to proceed with its disposal. Yasue, who runs a house rental service company in G...

Abayomi Nurain Mumuni, has voiced strong criticism regarding the performance of African leaders during the ongoing United Nations General Assembly (UNGA).

Trends in New Clinic Establishment Recent data reveals a notable trend in the establishment of new clinics, particularly highlighting a concentration in specific medical fields. Local hospitals and clinics are increasingly focusing on areas such as internal medicine and orthopedic surgery. However, one of the essential medical subjects—pediatric and adolescent medicine—has seen a continuous decline in the number of newly established clinics. According to an analysis conducted by Rep. Kim Mi-ae from the People Power Party and the Health and Welfare Committee of the National Assembly, based on data from the Health Insurance Review & Assessment Service, general practitioners, internal medicine, and orthopedic surgery have consistently ranked at the top among newly established clinics from 2019 to January-August 2025. For the first eight months of this year, the numbers were 531 general practitioner clinics, followed by 146 internal medicine clinics and 115 orthopedic surgery clinic...
