OpenAI confirms ChatGPT is down as logins and signups fail

ChatGPT is experiencing a major outage, and users are unable to sign in, create accounts, or load chats, including previous conversations. The outage started at approximately 8 PM ET on Wednesday, August 19, and is affecting users worldwide, including those in the US and Europe. If you are affected, ChatGPT will get stuck at loading animations for the sidebar, and you won't be able to send messages due to "too many concurrent requests" errors. New signups and logins on chatgpt.com are also failing. This outage also affects OpenAI's coding platform, Codex. Thankfully, OpenAI is aware of these issues and has already acknowledged them on the status page. OpenAI says it has identified that users are running into login issues across the impacted services, and that it is "working on implementing a mitigation."

Nothing here needs
