Same is happening to my site. I changed my DNS or my home computer to Google DNS and problem solved . But all my customers looking to spend that Christmas money that have comcast cant get to my site …. It is definatly a Comcast DNS I also pay for a deticated IP address so I am not shared with other sites .

Yeah, one more step towards censorship. I just renewed my subscription with http://www.sunvpn.com/, I usually use it when I travel, but it seems that I also need it back home.

Whatever it was, it’s fixed now. I definitely don’t like the way Comcast handles things. I’m glad I live out of range of their services, but I kind of hate that we’re still stuck with it in the office… We switched to Comcast just last week; I guess it’s a good thing, though, because we otherwise wouldn’t have noticed the problem.

It may very well be something at your web host however it is on comcast To communicate what the issue with it. Blocking without notice and no explanation is unacceptable in any environment Come on in my opinon.

The Networking guy is convinced it’s a host issue and is putting my webhost through the ringer in trying to figure out what’s wrong. Meanwhile, we’re still sitting here “in the dark” for all of our potential customers using comcast and our entire office (which has comcast) so I’m the only one getting email (because I have CLEAR) in the entire office other than those using their phones.

Yes, I think this is clearly a Comcast issue, because they likely can’t even tell you what they’re doing or why they’re doing it. To blame it on the host is unfair – although i realize that coming from a host it may not mean much to your co-workers – but a host cant possibly be expected to screen and make judgments about who uses their services. Being “strict” beyond spam guidelines would likely get us sued!

If Comcast blocked in a way they feel was legitimate, then they really should be able to tell you why, so the host can fix something if necessary, or help you get to the bottom of it. Your host can only act upon what Comcast recommends – either that, or as in our case, Comcast finally says “whoops, sorry. and will fix it… Good luck!

Our company is having this same problem today. Our networking guy says the problem points to our hosting server, but after finding this post I updated him (he’s talking to a Comcast buddy of his in person) and hopefully we can get this resolved. We’re a busy Real Estate company and the entire office is frustrated at their inability to work. Our website and email is blocked. I can access everything on my laptop because I have CLEAR broadband built-in, but nothing comcast-related is working.

One option we’re considering for the long-term insurance that this won’t happen again is purchasing a dedicated IP service from our hosting provider.

This whole situation is very stressful and confusing. I convinced my office to switch to our current hosting provider because all of my websites at home (I’m the web developer for the company) have been using it for a couple of years with amazing results… Now some people in the office are saying that it’s the host’s fault for not being strict enough about who they host and that we need to change again. My judgement is getting put into question and my credibility is being scrutinized because of comcast’s problem. Not cool.

Eric – Comcast doesn’t do any of that stuff – what would be the objective? This site is accessible from the Comcast network. Most times when we see these reports there are ACL or bogons lists causing problems at the web hosting site. You can of course investigate this by pinging the site and doing a traceroute.

Also, a local Comcast office is not really equipped to deal with these issues (nor is a comment in a blog post from 2009 either). I recommend you go to http://forums.comcast.net or http://www.dslreports.com/forum/comcast.

Hi Robert, just testing from my Comcast location (Lawrenceville, GA as reported by IP source) and both sites are viewable. I really think Comcast is blocking sites like California has had rolling blackouts. I’ve read about (internet) black holes and this may be just how it is happening. Instead of completely disconnecting you (or me when I’m having troubles), they just cut the lines to some part of the internet. This black hole is more insidious than a line cut however as usually packets go in and nothing comes out. Most things allow for an error to indicate a problem, but I’m now suspecting at least some of these reported black holes are intentional. Good luck with phoning the local Comcast office! Eric
