Its looks like you have a problem on your end. Maybe you should try to used proxies or try to use Tor to see if you can access blockchain.info. I can access my blockchain wallet, although I don't have bitcoin it in because I want to put my precious bitcoin in them for fear of security breach. I just created a wallet before when I was a newbie. If in any case you access your wallet, I suggest you transfer it to a wallet where you have control of the private keys like Electrum or Bitcoin Core. Just be sure to get it from trusted site and get the latest version. Goodluck.
