Occasionally, employees leave the company. When this happens, you can suspend their GitHub Enterprise accounts to open up seats in your site license while preserving the issues, comments, repositories, gists, and other data they created. Suspended users cannot sign into your installation, nor can they push or pull code.
Users are not notified when they are suspended and will receive the following error message if they attempt to pull from or push to a repository:
ERROR: Your account is suspended. Please check with your installation administrator. fatal: The remote end hung up unexpectedly
