Always keep a copy of Github repo as a Gitlab repo. Learn about git remote-add. Github was DDOSd a few months back, don't let that stop your work.
Mostly I agree except for the bit about Github being DDOS'd "stopping work". I never understood quite how the same people who were chomping at the bit declaring "git is our saviour" 5 years ago, are the same people who now claim to be "unable to work" because GitHub is not available...
If you rely on those parts of GitHub and it gets DOS'd, your workflow suffers.
