K MANGA emergency security maintenance interrupts digital reading services

Kodansha's K MANGA service, which serves U.S. readers, entered emergency maintenance on October 21, 2026, for a critical security update. Its official notice said all services would be temporarily unavailable and new chapter releases could be delayed. On October 22, K MANGA announced that the emergency maintenance was complete and all services were back online. Reporting linked the shutdown to the response to critical PHP vulnerabilities; the official notices did not establish exploitation, unauthorized access or data compromise. The precise restoration time remains unestablished.
