The official website of the ruling Bharatiya Janata Party (BJP) hacked by an unknown group on Tuesday. The homepage of the website displayed a meme of Prime Minister Narendra with Germany Chancellor Angela Merkel. Following the attack, the website - http://www.bjp.org/ - showed Error 522 Connection Timed Out.
The Error 522 means that the request was able to connect to your web server, but that the request didn't finish. The most likely cause is that something on your server is hogging resources.
