Hey everyone!
So Vanity Pool has been a bit broken for the last two months - Blockchain.info decided to make their web API require some client installation, but since my site runs on Google App Engine, I was no longer able to use it.
Since then I updated the backend code and switched over to using Block Cypher's API instead. I finished updating the code today and now the whole site should be up and running properly.
Sorry for any inconvenience you might've experienced.
