It says exactly that in the article:
> This week, we discovered that GitHub.com’s RSA SSH private key was briefly exposed in a public GitHub repository
Hilarious.
I didn't read it fully before commenting. I'm sorry.
If everyone read the entire article of each HN submission the comments section would be wildly different :-)
I can’t see that could ever happen. Is the key just floating around on their employees computers and skeins accidentally committed it?
Maybe because the article says so?

How do you know this?
Github runs scanner for private keys in public and private repos and notifies owner (I did it once so I know ... ;)). So some Github engineer likely would have received such an email if what you say is true. Hilarious.
