I'm not sure why I'm posting this, since the folks who need to see it can't make it to the page, but I am hearing from a number of readers who can't access the site via Comcast's new cable modem network. I'm not certain whether the problem is DNS or routing, but I know we can't fix either thing from here at TR. You might try this free web proxy for the time being.
Are any of you out there having this problem? I understand it's much more than just TR that's affected. How widespread is it?
