OpenAI’s systems are back to full operational status following a service degradation on September 3 that knocked out key functionality across ChatGPT and Codex. The disruption affected at least 15 components, ranging from basic conversations and logins to search, file uploads, and image generation.
The timing was particularly inconvenient. OpenAI had been actively teasing the launch of its GPT-6 Astra model, building anticipation among its user base right as the infrastructure underneath started buckling.
What happened on September 3
The main incident kicked off around 2:56 PM UTC, when OpenAI’s status page flipped to “degraded performance.” Error rates spiked across the platform, locking users out of core features that millions rely on daily for work and development tasks.
It wasn’t even the first hiccup of the day. Earlier that same morning, a separate incident caused high error rates within ChatGPT’s Work Mode. That one was comparatively minor, resolved in roughly five to six minutes by 12:10 AM UTC.
