Chris Wanstrath outlines strategies in a Disaster Guide, mirrored on his personal blog, that detail how to maintain access to your repository if GitHub encounters issues. He emphasizes the importance of pushing to a second remote, as GitHub is merely one node in a network, and suggests setting up an authenticated SSH server for additional security and accessibility.
