Tonight there is a wide spread Comcast internet outage all over the east Coast. This problem is being caused by a problem with Comcast’s DNS servers. A quick and easy way to fix this is to change the DNS servers your local computer is using from the default to Google Open DNS which is 220.127.116.11 and 18.104.22.168 . I am using a Windows Vista Machine right now so it is the only one I know how to do this on but I am thinking most windows versions will be about the same.
To do this in vista go to
Network and sharing center->manage network connections
Now you should see all of your network connections. Right click on the active connection (the one getting you on the internet) and click properties then internet Protocol version 4, once highlighted click on properties. Under the general tab click the radio button for Use the following DNS server addresses and put in the following numbers
Now click OK, restart your browser and you should be online.
