"PHP disclosed two critical vulnerabilities in their programming language and urged web site operators to immediately apply the fix," writes longtime Slashdot reader smooth wombat. "As a result, government web sites in Europe and elsewhere temporarily went dark on Wednesday as operators worked to protect their systems." The Independent reports: Dane Knecht, the chief technology officer of Web and cloud security firm Cloudflare, said that attacks were emerging and Cloudflare was updating its firewall rules as a stopgap measure.
