LinkedIn Enhanced Security Measures?

I logged into linkedin this morning and saw the security banner:

To change your password and take advantage of our enhanced security measures, click here.

I clicked on the link and it prompts for the email address. I enter email address click on the button.

It then tells me it emailed me and prompts to click the button to check my email. This takes me to hotmail but no email arrived. Even checked my Junk Mail. Is this enhanced security measure working? Are too many people clicking it that the email server is not keeping up?

I hope its the latter that would show the amount of people concerned about their security. I look forward to comments.

Did LinkedIn Get Hacked? Either way I recommend you change your password

Regardless of whether they got hacked or not. It is always a best practice to change

your password often on sites where you are sharing information.

Business Insider - LinkedIn Hacked

So either way, whether there was a hack or not I suggest you change your password for LinkedIn like I did.

Update: LinkedIn Did get hacked and they are suggesting steps to protect yourself.

Checkout the LinkedIn Blog for details.
