ChatGPT at capacity and can't use it. What's going on?

I have been unable to log in to ChatGPT for the last few hours. It says it’s at capacity (I’m a plus subscriber) Anyone knows what’s going on and when it’s likely to be resolved? Thanks.

Currently, it says it should be back up and running, but it hasn’t for me yet. They are planning to output a postmortem though, so hang tight.

It’s back for me now. Will be interesting to hear what happened.
