And to think blockchain.info almost got hacked yesterday. The hacker was trying to get the login details of customers, luckily for blockchain.info, it got aware of it quickly and the site went down for a while... they've not given anyone the go ahead to login yet.
I think the problem was hacker changed their DNS server for domain name, actually their domain registar account got hacked according to them. Still using blockchain.info don't know what could be next good alternative for blockchain.
