Sorry about the downtime guys, the previous hosting provider suddenly closed down and I had some unexpected issues with the migration to a new host.
I've tidied up the code a little, rehosted some images that had randomly disappeared from imgur (!?), and fixed some DNS and SSL issues ..
And now steemviz is a public github repository , served via netflify CDN - available at
https://steemviz.com

It's a realtime blockchain viewer and curation tool for steem - new users can find more info about steemviz here.
Here's a snapshot of the latest stats , we're passing 113k registered accounts and I have a feeling that's about to surge again as people begin to release how bad censorship of social media has become.

I'm open to any bug reports , pull-requests and feature requests!
