Always remember blockchain.info is owned partly by Google. They invested $40,000,000 into it a few months ago. Any small issues like this are nothing to worry about. If it goes down permanently, I assure you it would cause huge turbulence in the community. Chances are it won't anytime soon... 
I didn't read or even see this artilce's headline where you get this? Can you show us reference/source link saying this.And to OP, you only have to wait or reload the page when it happens since blockchain do have some unexpected maintenance or you can't login due to this or even the same with your situation, so there's no need to worry just wait. Tho I didn't recemmend to use this kind of wallet because of this.
what i actually do is get the nodes list and try to add them in my node
