xAI is investigating a service disruption affecting Grok, its generative AI chatbot developed by Elon Musk. Three major incidents have hit the platform in six months, with the most recent occurring on August 17 and lasting 1 hour and 30 minutes, caused by a GPU cluster issue affecting grok-4.6 and grok-4.5 models. A previous major outage lasted 2 hours and 24 minutes in March, and another disruption of about 1 hour struck on July 1. As of September 3, official status pages showed zero active disruptions, though independent monitoring platforms like Downdetector and Tickerr logged scattered user reports. Grok’s architecture with only one listed API region (us-east-1) raises questions about geographic redundancy and vulnerability to localized failures.
