Is Grok down right now?
This page tracks the current status of Grok, xAI's AI assistant available on X (formerly Twitter), at grok.com, and through the xAI API. The indicator at the top is refreshed every 60 seconds against xAI's official status feed and combined with user-submitted reports. Green means the assistant is responding normally. Amber means it is degraded. Red means a major incident is in progress.
Grok is unusual among major AI assistants because it lives across three distinct surfaces — the X integration, the standalone Grok web app, and the developer API — and any of these can be down independently. When people say "Grok is down," they usually mean the X integration, which is by far the highest-traffic surface.
Grok outage history and common causes
Grok's reliability profile is shaped by its tight coupling to X. The X integration depends on X's authentication system, X's frontend, and xAI's model serving all working at the same time, so any of those failing causes a Grok outage. Outages on the X side are particularly common because X has had ongoing infrastructure changes since the platform's rebrand.
Specific recurring causes: capacity overloads after major Grok feature launches (Grok 3 and 4 each caused short bursts of unavailability), authentication issues tied to X's login system, regional issues in xAI's serving infrastructure, and feature-specific breakage where the chat works but image generation, voice mode, or DeepSearch fails. The xAI API has its own failure surface and tends to be more stable than the consumer surfaces because it has fewer dependencies.
Is Grok reliable?
Grok is the youngest of the major AI assistants and its uptime reflects that — independent monitoring tracks 30-day availability somewhere in the 99.0 to 99.5 percent range, materially behind the more mature offerings from OpenAI, Anthropic, and Google. The reliability has improved meaningfully across each model generation, but Grok is still not in the same uptime class as the leaders.
For most use cases this is fine because Grok's user base treats it as an interesting alternative rather than a primary tool. If you do rely on it, the xAI API is the more stable option, and the practical advice is the same as for every other AI assistant: keep at least one alternative open. ChatGPT and Claude are the most direct substitutes.
What to do when Grok is down
First, check the indicator at the top of this page. If it is red, the issue is on xAI's side. If it is green but Grok is broken specifically inside X, the issue is more likely with X's frontend than with the model itself.
Second, try a different surface. If the X integration is broken, grok.com often still works. If grok.com is down, the X integration may still work. The xAI API is the most stable surface and is worth trying if you have a developer key.
Third, switch tools. ChatGPT and Claude can handle most of the same tasks. Gemini and Perplexity are good fallbacks for search-grounded questions, which is one of Grok's strengths via DeepSearch.
Finally, report the outage here. The user-report counter is the fastest public signal of actual service health and helps the next person who lands on this page figure out whether to wait or move on.
