What our checks recorded

We checked Grok 13 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 147 ms, against 151 ms over the 24 hours before. xAI posted the incident at Oct 29, 9:45 PM EDT.

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

Grok depends on xAI. When that upstream has an incident, it doesn't hit Grok alone — these AI tools share the dependency and can degrade at the same time:
