Massive problems with authentication on github.com

There are massive problems with authentication on the site github.com
According to user reports, the problem arose this weekend, starting from Saturday 04/13/2024.

Essence:
After the login and password have been entered correctly, the system sends an authentication code by email. However, the code itself does not arrive or arrives with a delay of more than 6 hours. Thus, authorization fails.
The problem is not tied to geography.

Due to the nature of the site, users are unable to report their problem if they are not authorized. However, the problem lies precisely in the fact that the user authorization system has failed.
Some users create a new account just to report a problem.

The current status of the problem is available at the link:
