A few resources I regularly go back to

Troy Hunt - If you have even a passing interest in InfoSec, check out Troy's blog. A massive amount of excellent information about web application security, among other things.

Have I Been Pwned - An excellent resource for individuals and business alike for keeping track of the seemingly inevitable occurrence of being caught in a data breach.

Hak5 - Excellent online media covering everything from open source software and network infrastructure to pen testing... and the makers of some cool hardware like the Rubber Ducky!

SSL Labs - Go and get your certificate configuration checked out.

Wayback Machine - Check out how bad the internet used to look!
