Why is ChatGPT Down Today? Possible Reasons

OpenAI has not yet released a detailed root cause, but based on the pattern and past incidents, common causes for such spikes include:

• Backend infrastructure issues — Problems with servers hosting the ChatGPT web interface or Codex model.
• High traffic or load balancing failures — Sudden demand surges can overwhelm specific components.
• Recent deployment or update glitches — Issues often arise after model updates, feature rollouts, or maintenance.
• API and integration problems — Affecting developers and business users relying on programmatic access.
