Server error 503 (Service Unavailable)

From two days ago until now I can not connect to the package manager, while two days ago it worked fine, but now it gives a 503 error or it is time out.
at first I thought it was a problem with my system and with a few vpn I tried to connect to the package manager but to no avail.
then I went to this site and realized that it seems to be a problem with the server and a global problem.

What should I do now?

A 503 Service Unavailable Error is an HTTP response status code indicating that your web server operates properly, but it can't temporarily handle the request at the moment. This error happen for a wide variety of reasons. Normally, this error can be due to a temporary overloading or maintenance being performed on the server and it is resolved after a period of time or once another thread has been released by web-server application. In most cases this could happen (assuming there are no faults in your app) if there are long running tasks and as a result the request queue is backed up. Almost always, the 503 Service Unavailable Error is on the website itself and there's nothing you can do about it but try again later.

 

I'm having this problem just now. Can't see any of my assets in package Manager.

I can't access any of my account menus, can't see my purchase history, my saved assets, anything.
