Unable to initiate or continue new or existing chats ChatGPT App. Complete service outage

ChatGPT/Codex are all down currently, it's not a Codex-specific sub issue

unexpected status 503 Service Unavailable

I also encountered the same problem.

https://status.openai.com/incidents/01KYC921K145JTR1JK7DYKGWH1

Seems like all system got shut down. Plugins do not load, settings do not work, avatar in ChatGPT web app does not load, it says I can upgrade plan despite being on Pro x20, chat does not answer at all (previously got 500 No shard mapper found while working with my MCP plugin). Seems more like most of OAI infra is down

same problem

I am also experiencing the same issue. This is what my codex says. I just sent /feedback

Why hasn't anyone taken responsibility for such a serious and completely paralyzed situation?

Why hasn't anyone taken responsibility for such a serious and completely paralyzed situation?

Currently everything is down, not just Codex

Same issue

I thought I was the only one who encounter this. LOL

Same problem

我他妈，刚重置，这又是要送了？

我也一样。看来确实又要送重置了

same

Thirty five minutes since first report and it's still down. I can't believe such a huge system laid all at once

Somebody should get fired for terrible system design

When will it be fixed?

Same 503 issue

Oh, I specifically logged out and found that I couldn't even log in anymore. Good thing GitHub isn't down.

This problem still persists. I find that it has not been completely resolved：

Second incident 😅 https://status.openai.com/incidents/01KYCGY017EG43XZS6GFVXA8VH

seem to be fixed for me via opencode
