In April, I blogged about the possibility of many computers here in the US losing the ability to connect to the Net. I won't go into all the details again, but if you want to read all about it, here is the link to my original post.
Today's post is short, but very, very important. To ensure that your computer is not at risk of this problem, paste the following link into your address bar on your browser: http://www.dns-ok.us/
It will take a look at things and let you know if you are OK or not.
The good news is that I've run it on every computer and I seem to be OK. Whew!
