WebMd Blacklisted by comodo DNS??

I tried to visit webmd but it keeps giving me a “server not found” error.
Is webmd blacklisted my comodo dns??

You can go back to your ISP’s DNS servers and see if the same thing happens or not. When it happens then the site is down. When it doesn’t the site gets blocked.

Its not black listed on my original ISP DNS. Its only black listed by comodo.
Why would webmd be blacklisted? The site is a legit site that is there to help.

That must be a false positive then. It should not be blocked when it is a safe site. Not sure though how to submit this so it can be set straight.
