When you click Run button on dlang.dzfl.pl, ajax makes POST 
request to local process.php (can be any scripting language, 
probably making it js-only could work with some iframes-hacking). 
Then it requests http://dpaste.dzfl.pl API via POST and it 
returns JSON with response.

http://dpaste.dzfl.pl service resides on unaffected server, while 
compiler service resides on 4 (hope to add more mirrors in near 
future) machines. I've implemented small load balancer in D.

Whole infrastructure is written in D and uses different 
approaches, containers on linux mirrors and jails on freebsd 
mirrors.

Each request has limited resources, execution time, IO access etc.

Website itself (http://dpaste.dzfl.pl) is written in PHP, but I 
am thinking about switching to D in near future (not sure what 
framework pick up yet, vibe.d, serenity or own implementation).

If you want to know more details, let me know
