What our checks recorded

We checked Grok 3 times from xAI's start time to its resolution, once every five minutes. Every one of them reached Grok'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 189 ms, against 219 ms over the 24 hours before. xAI posted the incident at Sep 10, 3:03 AM EDT.

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