Claude (Anthropic) from China: Web, API & Safety Tips
Why Claude can be unstable
Anthropic enforces region and abuse policies. Direct access to claude.ai or APIs may fail with verification loops or “service unavailable.” Datacenter or heavily shared IPs can trigger checks—similar themes to ChatGPT access, but rules differ.
What you need
A modern client with split routing or global mode; a stable, low-abuse exit; consistent proxy for browser and terminal when using APIs. Plans: Plans.
