Cloudflare $NET ( ▲ 1.5% ) ran into trouble again on Friday after a change to how its Web Application Firewall parses requests caused parts of its network to go offline for several minutes. The company said it implemented a fix about 20 minutes later, helping limit the damage after the stock fell as much as 6 percent in premarket trading. Shares are now down about 2 percent.
The outage temporarily knocked out access to major platforms like LinkedIn, Zoom, Fortnite, Shopify, and Coinbase. Users might have reported even more issues, but Downdetector also went down during the incident, according to The Verge.
This is Cloudflare’s second major outage in a month. In November, its network went offline for roughly three hours and took OpenAI, X, and League of Legends with it. That came shortly after a 15-hour Amazon Web Services outage in October disrupted wide swaths of the internet.
