What our checks recorded
We checked Grok 18 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 182 ms, against 202 ms over the 24 hours before. xAI posted the incident at Aug 17, 5:57 PM EDT.
