It's not an official bitcoin wallet , the only wallet that could be considered as an official wallet is "Bitcoin Core" which got created by Satoshi Nakamoto and now maintained by the developers. It's possible to take down the website by both hacking & DDOS attacks and It happened before.
edit.. i can't access the wallet.. maybe turkey banned blockchain. god. never had any problems before. i have more than 4 btc in my wallet.
Relax , It seems like they indeed have somes issues , I just checked their twitter account (tweeted 8 minutes ago) :
