Juts few days ago blockchain changed their domain from blockchain.info to blockchain.com and also declared a warning that their users should bookmark the new domain to avoide any feature funy situation.
The reason behind this new change is still uknown to us but i think this new domain is cooler than the previouse one and we hope they provide us with more features and services.
Please indevour to always signin to your bitcoin wallet with blockchain.com rather that blockchain.info to avoid hackers taking hold of your account.
