Cloudflare rolls out fix after another significant global outage

(Sharecast News) - Cloudflare suffered a significant outage on Friday that disrupted access to a wide range of major websites and services, marking its second major incident in less than a month.
Platforms including LinkedIn, Zoom, Canva, Shopify, Coinbase, and gaming services such as Fortnite were briefly rendered inaccessible.
Many users attempting to load pages were met with blank screens or '500 Internal Server Error' warnings, and even outage-tracking site DownDetector was knocked offline before it recovered.
The company said the disruption originated from issues with its Dashboard and related APIs, triggered by a change to how its Web Application Firewall processed requests.
Cloudflare stressed the incident was not the result of a cyberattack, explaining the update had been deployed to mitigate a newly disclosed industry-wide vulnerability.
The firm rolled out a fix within about 30 minutes and said services were returning to normal, although some features continued to experience degraded performance.
Cloudflare provides network security and internet traffic management services used by an estimated fifth of all websites worldwide, meaning problems at the company can have outsized effects across the web.
Friday's problems followed a similar outage in late November that took numerous platforms offline for hours, prompting Cloudflare's leadership to apologise and reiterate its systems were designed for resilience.
The recurring disruptions have intensified scrutiny of the growing reliance on a small number of infrastructure providers that sit between users and the services they access online.
Cybersecurity specialists warned that the concentration of such functions represents a structural weakness, leaving businesses exposed when errors occur in a single provider's systems.
Cloudflare shares fell sharply in premarket trading as news of the latest outage spread, though losses eased after the company confirmed the issue had been resolved.
At 0937 ET (1437 GMT), shares in Cloudflare were down 0.69% in New York at $202.65.
