What our checks recorded

We checked ChatGPT 21 times from OpenAI's start time to its last update, once every five minutes. Every one of them reached ChatGPT's site, so this incident did not show up as a failed page load. Our check loads the public site; it cannot see an API error or a broken feature. Median response time was 449 ms, against 381 ms over the 24 hours before. OpenAI posted the incident at Nov 5, 10:25 AM EST.

Updates are OpenAI's own words from its status page (status: monitoring); we never add an inferred cause.
