  • ShieldsUP! has been overloaded by LifeHacker!!

    We’re sorry to have to pull the service down, but the MASSIVE FLOOD of users sent to us by the mention on Lifehacker (which we TOTALLY appreciate!), coupled with the length of time (a few minutes) to test all ports, can possibly be serviced. Once the massive wave of usage has passed we’ll be able to put ShieldsUP! back online and we sincerely hope you’ll give it a try. But for the time being we’re just too swamped! Sorry!!

  • GRC’s ‘ShieldsUp!’ test is literally 7 or 8 years old by now….. Is this really news? :\

    Also, the test is down at the moment due to the traffic generated by this.

  • Um, you broke it guys! They have taken the service down (temporarily) due to the flood of traffic generated by your article.

    Good to know that people read your articles! 🙂

  • the site is displaying a page that says:
    “We are SO SORRY to have to temporarily take the service offline — which has been up for many years and has performed more than 83 million port security scans for people.

    But we cannot possibly service the MASSIVE FLOOD of users sent to us by its April 7th, 3:00pm mention on Lifehacker (which we TOTALLY appreciate by the way!) due to the length of time (about a minute or so) required to test each visitor’s ports.

    Once the massive wave of usage has passed, we’ll be able to put ShieldsUP! back online and we sincerely hope you’ll come back and give it a try! But for the time being we are just too swamped! Sorry!!”

    looks like ill have to wait till the site is back up and running at full steam…

  • It appears that the GRC website is no longer running any tests due to it getting slashdotted (lifehackered?).
