Rancak Media – JAKARTA — Cloudflare Inc.’s stock plummeted in pre-market trading on Tuesday (November 18, 2025), following a global network disruption experienced by the prominent cybersecurity firm. This significant outage crippled access to numerous websites and essential digital services worldwide.
Bloomberg reported that Cloudflare shares dipped by approximately 4% ahead of the U.S. market open, reflecting growing investor concerns regarding the extensive scale of the disruption and its potential business ramifications for the company.
As widely reported, the outage rendered several popular services inaccessible. Among those affected were AI chatbot ChatGPT, social media giant X, the website for the U.S. primary energy regulator Federal Energy Regulatory Commission (FERC), and financial data and ratings provider Moody’s Corp.
A Cloudflare spokesperson stated that the company detected an unusual surge in traffic directed at one of its services around 6:20 AM ET (18:20 WIB).
“…which caused some traffic traversing its network to experience disruptions,” the spokesperson explained, as reported by Bloomberg.
Despite Cloudflare officially affirming its diligent efforts to restore services and ensure the disruption’s resolution, many websites, including Moody’s Corp.’s site, remained inaccessible for an extended period. The company admitted to ongoing challenges in identifying the root cause.
“We have not yet identified the cause of this unusual traffic surge,” the spokesperson added, emphasizing their commitment. “We are all working diligently to ensure all traffic is served without disruption.”
A Series of Cloudflare Network Disruptions
Bloomberg also highlighted that Cloudflare has encountered several significant network disruptions in recent years, underscoring a recurring challenge for the critical internet infrastructure provider.
In July 2019, for instance, a software bug within Cloudflare caused a segment of its network to consume excessive computational resources, rendering thousands of websites worldwide, including Discord, Shopify Inc., SoundCloud, and Coinbase, offline for up to 30 minutes. More recently, in June 2022, Cloudflare faced another extensive outage impacting traffic across 19 of its data centers.
This incident in 2022 “…effectively shut down major websites and services for approximately one and a half hours,” Bloomberg’s report detailed, showcasing the widespread impact such disruptions can have.
It is well-known that Cloudflare’s software is utilized by hundreds of thousands of companies globally. The platform functions as a crucial buffer between websites and end-users, diligently safeguarding them from traffic-overloading attacks and other malicious threats. Its widespread adoption highlights its pivotal role in maintaining internet stability and security.
This Cloudflare outage draws parallels to another major incident last year, when a faulty software update from cybersecurity firm CrowdStrike Holdings Inc. incapacitated millions of devices running on Microsoft Corp.’s Windows system. That event caused widespread disruption across various industries, including air travel, banking, and healthcare, illustrating the ripple effect of system vulnerabilities.
“This disruption serves as the latest illustration of the internet’s increasing reliance on a relatively small number of players,” remarked Alan Woodward, a cybersecurity professor at the University of Surrey, commenting on the broader implications of such events.
“People simply have no choice but to depend on a relatively small handful of major names,” Woodward concluded, underscoring the inherent centralization of critical internet services and the vulnerabilities it creates.
Summary
Cloudflare Inc. mengalami gangguan jaringan global pada Selasa, 18 November 2025, yang menyebabkan harga sahamnya anjlok sekitar 4%. Gangguan signifikan ini melumpuhkan akses ke berbagai situs web dan layanan digital penting di seluruh dunia, termasuk ChatGPT, X, dan Moody’s Corp. Cloudflare mendeteksi lonjakan lalu lintas yang tidak biasa tetapi belum mengidentifikasi penyebab utamanya, meskipun mereka berupaya keras memulihkan layanan.
Insiden ini bukan yang pertama, karena Cloudflare telah menghadapi beberapa gangguan jaringan signifikan dalam beberapa tahun terakhir, seperti pada Juli 2019 dan Juni 2022. Dampak luas dari gangguan tersebut menyoroti ketergantungan internet yang semakin besar pada sejumlah kecil penyedia infrastruktur penting seperti Cloudflare, menunjukkan adanya kerentanan sistem yang melekat.
