Broadband forum: Comcast blocking legit sites now!?!?

Thanks for attempting to point out the obvious.

I have tried to resolve based on IP rather than by domain name. And, NO, it will not resolve while using Comcast as the ISP.

So, it is doubtfully a Domain Name Server issue.

I live in metro Atlanta area and I see that web address fine. I copied and pasted the www address srraight from your post into my web browswer. Shows just fine.

I did not know about OpenDNS. Thanks!

i don't think he's taking it out on you; you seem to be perturbed by his postings instead. ease up--not all of us are adept at handling these issues. comcast IS a pain for us who are less experienced. my ie7 keeps crashing (for example). i hope you're not so harsh with everyone else. hope your day gets better, man..........

Just a bit off topic question. Since we both have the same locale and profession, I was curious as to your opinion of Comcast cable internet service. I have been with Bell South DSL for 5 or 6 years, but am considering a switch to Comcast because of speed and price considerations.

Thanks

This is a problem everywhere with every ISP. Until relatively recently, Comcast, like other ISPs, operated their Internet service like Frame Relay. There was no security at all. Now, Comcast has since turned 180 degrees and is actively securing their leg of the Internet. But, sometimes, they go too far. In Comcast's defense (I am only a customer), I experience the same problems with other ISPs and even at my office -- system administrators blocking web sites and sometimes entire IP blocks. If you talk to a system administrator about this, you will find out that this is very muddy water and I feel sorry for the administrators because they receive so much flak.

it could be your computer. Try deleteing Your HOSTS file.

for a year, I used to be able to access thottbot.com, and then one weekend it just stopped resolving - Cannot Find Server. I tried calling support, no help - must be user error - noobs.

I switched to verizon fios and can access the website again. Thottbot.com does do some strange DNS routing and web-farming, but should Comcast be implementing a DNS strategy that "usually" resolves to IPs?

My broadband provider is Adelphia, which provides an excellent 5 meg broadband service. It's never down and works great. BUT, occasionally I can't reach favorite sites.
One time, when I couldn't reach HGTV.com, I called support. The support office is in Pennsylvannia, and I asked the support person if she could reach HGTV.com. She could. So she looked up which DNS server she was using, and, indeed, it was different from mine. I already knew that my local DNS server in Ven Nuys, Calif., is cranky--this had happened before--and, indeed, any Adelphia customer in the Western half of the United States could not reach HGTV.com that day. She was kind enough to give me the IP address of an Adelphia DNS server in Virginia, one that appears to be less cranky. So, I use that on those rare times when I can't reach an important site.
The DNS issue that's happening appears to be some problem with getting updates from certain other DNS servers. The Adelphia server was reporting failures in getting DNS information from HGTV.com's hosting company, BellSouth. After a bunch of phone calls and emails, I'm still not sure who had the problem, Adelphia or BellSouth (and it's almost impossible to assign blame confidently in these IP incidents). It may be a software issue between the two servers. Who knows.
The lession here is, before you start to think about Big Brother, check out DNS issues.

I have emailed a message and was sent back by postmaster general "UNDELIVERED"

Damn it. Sorry I didn't see the date on the post. The forums sometimes default to page 2 instead of the first page.

Again, sorry.

This happens to me as well. Seemingly at random... Just today I was unable to view a client's website on my work PC (or any pc in-house for that matter). I then pulled it up with my smartphone. I unplugged the Comcast modem for 10 seconds and plugged it back in. BINGO! Back in business.

Comcast isn't doing this intentionally, folks. Comcast leases out horrible hardware at premium prices and we just smile and ask for more. Who is really at fault here?

Absolutely!

Comcast is blocking my site which I use for my classes in chemistry. The reason may be that it has the extension ".net" which might look like a competitor. The site is available by any other route except Comcast.

Comcast, of course, denies this, so I can't get it fixed. This is a real problem for my student, much less for me, since I can't unload through Comcast.

I will recommend to all my student to get some other service than Comcast. I recommend to all out there to do the same.

I forgot to mention that I have also tried the IP address.
