It's not the first time blockchain.info has been down for a prolonged period. While they have awesome UI and reports, it seems like their stability and disaster recovery is letting them down.

To be fair there are plenty of block explorers and blockchain.info isn't even my favorite one, its hardly not a good sign for the ecosystem of Bitcoin if a website goes down, don't be so dramatic.
