Why would this be happening to my Fluther account?

I had Comcast come about a week ago and give me a new modem (which is also the router now) and new DVR. Everything works fine, or so I thought.

For about two days, no problems. Then, I noticed when I am on Fluther and go to my “New Activity,” the search bar says “Fluther new activity” and then switches over to “Comcast new activation.” It brings me to a Comcast page.

I had that for about two days last week. It was frustrating as I couldn’t check my new activity, except from my phone or when I go on the computer at work. Then the problem went away, and all was as it should be. This weekend, it came back. Some questions, when I click on the individual question to try to check it that way, I get the same thing.

This is something that never happened to me, before Comcast came. It doesn’t happen to other websites either. I don’t do a whole lot on my home computer, just usually FB, email and maybe the NY Times site and that’s about it, but regardless, it’s very weird and inexplicable.

Do you know what’s going on?
