Change your DNS server settings. I doubt it's intentional, but Comcast's DNS servers normally suck that bad anyway.
I'm on Comcast as well and have had no problems since I changed DNS servers.
Possibly. We have a LAN and frequently have problems linking to Conservative sites.
Wow - another new arrival from the future! I for one welcome our new time-traveling overlords.
I'll be watching you...
Try power cycling your router.
Open a command prompt and ping powerlineblog.com and see if you get an address back. That will rule out DNS.
I tried to ping "powerlineblog.com"... no luck. Please fill me in on how to change my Comcast DNS.

I have had the same problem. I power recycle both the modem and the router and them I can read Captain Ed again. This is not a problem restricted to Firefox, Mozilla, Opera or the dreaded MSIE. It also happens on Linux browsers. Recycling fixes the problem.
