Earlier this year, at the end of May, Blockchain.info suddenly experienced downtime as well for several hours. Users who wanted to access their wallet were unable to do so, causing a widespread panic among Bitcoin users worldwide. Just a few months later, another lengthy period of downtime ensued. It should come as no surprise to see many people switching to a different service, both for Bitcoin wallet and API purposes. Blockchain.info has become too unreliable in the past 12 months and something needs to be done rapidly.
Moral of the story.... Don't store your coins in a wallet where you do not have full control over your private keys. If you do have control over all your private keys you can always make use of another compatible wallet service to get your coins out should something like the above happen to your main wallet.
I guess the biggest problem for them [Blockchain.info] at this stage is hundreds if not thousands of users trying to import those private keys from the CoinWallet attack into their online wallets in order to try and claim some of those coins.
