GitHub.dev not response for several time and come back alive in few days

some weird thing happened on GitHub.dev

I don’t know if there is some operation that I have done wrong, which causes this problem, or the system just simply crashes, sometimes it works, but sometimes it doesn’t.

Background knowledge: github.dev is a web editor just like an online version of VS Code, to enter this editor just simply press the “.” button on your keyboard when you are inside your repository.

many thanks to any one who can tell me is that my fault or not .
