The interesting issue that I'm having currently with Blockchain.info, is when I'm trying to access my online wallet, it attempts to send a two-factor authentication email to my AIM mail account, but it never arrives, only very intermittently, coming into the spam folder.  But for the most part, I never get that email to authenticate my log in.  I keep wondering if the issue is with the AIM mail servers or blockchain.info  I never had any issues prior to this.    

*update*

Interesting to note that I finally did receive the email and was finaly able to log in using two-factor authentication.  I then decided to change my email address for future contact, and the verification email seems like it's being delayed, so the issue may be with blockchain.info.......just speculation.
