Hi Mario,

Sorry, that's an old link.

A long time ago, I used CloudFlare as a wrapper for the GitHub Pages
website.  They offered free https for both www. and plain domain.

Just over a year ago, GitHub started using Let's Encrypt to offer https.
I swapped over (to simplify my life).

> It seems like your Let's Encrypt cert has just one SAN

Even though Let's Encrypt support wildcard domains, GitHub only supported ONE.
So I decided to drop the 'www.' as it was a bit old-fashioned.

> and perhaps you should generate another cert which also includes www.

Instead, I updated every link that we had control over and notified
everyone that I could find.
