Codex Incident History

This archive holds 30 incidents tagged as affecting Codex, recorded between 7 April 2026 and 20 August 2026 – the second largest group on this site after consumer ChatGPT. 77% of them were Codex-only, so a Codex incident rarely tells you whether the ChatGPT app is working; the two usually move independently. When Codex does fail alongside something else it is most often ChatGPT (5 incidents) or the OpenAI API (3). Figures in this paragraph describe our own stored archive as of 31 August 2026; the archive begins on 7 April 2026, so earlier incidents are not represented.
