Popular social-networking site Facebook was hit with a DoS (denial-of-service) attack Thursday, but the attack did not appear to be as severe as one that crippled Twitter the same day.

"We have restored full access for most people," the company reported. "We'll keep monitoring the situation to make sure you have the reliable experience you expect from us."
