Recently, I noticed my public GitHub account & repositories were suddenly no longer publicly visible.
I have no clear view on the reasoning for this. I have opened a support and reinstate request, yet so far without clear feedback of GitHub, neither with corrective action.
Luckily, I still have access myself to all my private and public repo's. But it makes you realize the dependency you get on GitHub.
If anyone needs any repo, feel free to reach out by Twitter or mail (myTselection [at] gmail.com).
