# Claude AI, Cursor, and Amazon Q: Why Is Claude Down? > Source: > Published: 2026-06-06 22:16:55+00:00 Developers are increasingly relying on Large Language Models (LLMs) to accelerate workflows. While Claude AI, Cursor, and Amazon Q all leverage advanced transformer models, they serve different primary use cases in the software development lifecycle. Claude AI is a general-purpose conversational LLM often used via API by developer tools like Cursor to provide reasoning and code generation. It experiences downtime when Anthropic's API infrastructure faces high traffic loads or regional server outages, which ripples into services that depend on its backend. | Feature | Claude AI (Anthropic) | Cursor | Amazon Q | |---|---|---|---| Primary Use | Reasoning/Chat | IDE Integration | Enterprise/AWS | Model | Claude 3.5 Sonnet | Multi-model (inc. Claude) | Custom Amazon Models | Setup | Web/API | VS Code Fork | AWS Toolkit Plugin | When you see "Claude is down" messages in your IDE or browser, it is usually due to one of three factors: If you rely on Claude through Cursor, you can often mitigate downtime by switching models within the settings menu. Cursor supports multiple providers (like OpenAI's GPT-4o). Navigate to **Cursor Settings > Models** to toggle your provider. This keeps your workflow moving while the primary API recovers. Which AI coding assistant do you find most reliable when your primary service goes offline?
