pull down to refresh

I know puppy - I used to run this OS on some really old machines - a decade ago.
It's been so long since I visited the site - I must say, I did a double take on the URL.
Very cute and super fast - allows old machines to live a lot longer - but takes a bit of time to get used to.
I wonder why they're redirecting from the usual https://puppylinux.com/ to https://puppylinux-woof-ce.github.io/ now - any ideas why?
