On June 22nd, an incident affected ODC users in the US East (N. Virginia) region. Users were unable to access any applications in the Development stage, receiving an "Upstream Request Timeout" error. Production and Test stages, as well as all other regions, were unaffected.
The incident was caused by a platform configuration change that prevented the component responsible for starting idle Development-stage applications on demand from functioning. As a result, when a request arrived, the application failed to start, causing the connection to time out at the gateway.
The issue was resolved by reverting the configuration change. The component fully recovered, app startup resumed, and normal service operation was verified.
