Three major AI services went down within the same morning on 3 September, producing an unusual sequence of failures across ChatGPT, Claude and Grok. The timing quickly fuelled speculation that OpenAI's GPT-6 Astra rollout had overloaded its own systems and sent users towards rival models.
Anthropic first reported elevated errors around 6.23am Pacific Time, followed by Grok at about 6.30am PT. ChatGPT's main incident began around 7.43am PT, while Astra was announced later that day as a limited rollout.
