Yikes! Comcast seems to be blocking my business/author website

I'm developing an author website on a domain I've had for years. Never a problem. But yesterday, I couldn't reach my website www.robblightfoot.com on my Comcast WiFi. I can still "see" it on my cell phone's web-connection. I checked my email, and I see that comcast reportedly protected me from a "suspicious" site. I turned this off, and presto, it connects to me website again. 😞

 

I've been reading technical notes, an I ran a trace, listed below. I also got a security certificate for my site, and changed it over to load only as a secure site. I did this months ago and no problem. But I did have an issue, just before this happened, trying to connect an OLD version of Dreamweaver in my domain. I had a couple of dozen failed logins in the space of a few minutes. I don't know if this is a coincidence or what.

 

My concern is that Comcast has flagged my domain, robblightfoot.com. This is hosted with a unique IP on Dreamhost, and I don't know who to contact to resolve this. Should I just dump that IP and but another? Do I need to have DreamHost run an audit to see if the certificate has an issue with the underlying IP? I don't know who to talk to. I have Dreamhost scan this thing regularly for malware, and it reports clean. 

 

Can someone tell me who, at ComCast / Xfinity, to call regarding this? If it's a glitch in my certificate, I know I'll need to talk to at Dreamhost. But I suspect this won't just automatically resolve.

 

Any help would be appreciated. 

 

Here's the traceroute check
