It's looks like there is another phishing attempt going on using Blockchain.info
Many users including Reddit user fulber34 stated that he received an email from blockchain.info with the title as “Warning: Don’t get locked out of your blockchain” and it said that the website is upgrading their database, and they require the validation of users wallet details on their website. This can be another phishing scam as a blockchain website would never ask for validation of personal details.

People should never click any of those clicks, there is such thing as email redirection I was a victim of that my own I receive email using my domain name, it's better to login to your blockchain.info account and from there you can see their newsletter if they have maintenance ongoing, better check that if they have that inside the blockchain site.
