h11e.com is a challenge, so we used Azure and a 16core/224GB RAM Virtual Machine, wrote a script to solve the hashing problem, and fired it off. 20something hours later with 2 VMs running at 100% CPU, we're doing very well. We actually also used AWS as well and tried to use Bluemix but it wouldn't play along.
There isn't a link a link to it because it's a VM. Just ask us to show you.
