Claude’s AI chat service went offline for users in the UK and abroad on Tuesday 23 June 2026. Users encountered errors when they tried to start a chat. It in the early hours and spanned the entire world. When users gave it a go, the system produced faulty answers.
The team behind the service says they located the problem after checking the logs in the evening on Tuesday. They are observing traffic while they deploy a solution. They say the problem is expected to clear once they finish checking systems are functional again. People can retry once it stabilises.
