Is the PSP store still open?

Excuse me, I was wondering if you could clarify something for me. I've been trying to access the PSP store recently, but I'm not sure if it's still operational. Could you tell me if the PSP store is still open and accessible for users? I'm curious about the current status of the store and whether or not it's still possible to purchase games and other content from it. Thank you for your time and assistance.
