Ah roger that. Excited that it's back up an running -- was using it quite a bit previously. I'll check out the new updates shortly.
For someone that is interested in coding and developing things, where would you recommend as a good place to start with putting together a block-chain explorer application such as this? What was this written in? Python?
It's written in PHP and CodeIgniter. I released a small library on my Github and I integrated it in CodeIgniter MVC. The library is pure PHP, though, it's installable via Composer, so you can use it however you want.
