I have no idea what happened to KrinLabs. I couldn't go on it as well. I doubt it got hacked. As far as I'm concerned, there could be some construction going on KrinLabs.
Appears the site just ran out of its license or something, and didn't get renewed, so it's a parked page. ... Though this parked page happens to redirect to 127.0.0.1 apparently, which happens to be your local computer's IP. So...it's a useless page now
