Diagnosing Problems With Custom Domains - Case Study #6

In my previous custom domain case study, I presented a poorly working custom domain, where the "www" alias was properly setup, but the primary domain was using URL forwarding. Maybe it's a setup recommended by the DNS host technical support staff, who don't support "CNAME" referral for the primary domain.

Some DNS hosts just don't understand "CNAME" referrals, and the previous case doesn't show how badly domains can be setup.

Let's look at one case, again a fictional example "mydomain.com", setup using the "Advanced Settings" wizard.

There are 4 URLs to study here.
  1. The primary domain "mydomain.com".
  2. The "www" alias for the domain "www.mydomain.com".
  3. The primary BlogSpot URL "myblog.blogspot.com".
  4. The "www" alias for the BlogSpot URL "www.myblog.blogspot.com".


First, let's dig the DNS records for the primary domain "mydomain.com".
;; QUESTION SECTION:
;mydomain.com. IN A

;; ANSWER SECTION:
mydomain.com. 3600 IN A 64.202.189.170


Next, the "www" alias "www.mydomain.com".
;; QUESTION SECTION:
;www.mydomain.com. IN A

;; ANSWER SECTION:
www.mydomain.com. 3600 IN CNAME mydomain.com.
mydomain.com. 3600 IN A 64.202.189.170


And examine "64.202.189.170".
pwfwd-v01.prod.mesa1.secureserver.net (64.202.189.170)
64.202.160.0 - 64.202.191.255
GoDaddy.com, Inc.


The latter is using URL forwarding, to redirect "mydomain.com" to "myblog.blogspot.com", plus using a "CNAME" referral to direct "www.mydomain.com" to "mydomain.com" (and the URL forwarding). URL forwarding is preferred by some DNS hosts, who prefer to not to provide "CNAME" referral, but it's wrong when used in a custom domain setup. For Google Custom Domains, it will probably work, for a while, but unreliably so. Even if it works for a while, it will potentially cause problems, for everybody.

Stats Components Are Significant, In Their Own Context

One popular Stats related accessory, which displays pageview information to the public, is the "Popular Posts" gadget.

Popular Posts identifies from 1 to 10 of the most popular posts in the blog, by comparing Stats pageview counts. Optional parts of the display of each post are a snippet of text, and an ever popular thumbnail photo.

Like many Stats features, blog owners have found imaginative uses for "Popular Posts" - and overlook the limitations of the gadget. Both the dynamic nature of Stats, and the timing of the various pageview count recalculations, create confusion, when Popular Posts is examined.

Help! I Can't See My Blog!

I just posted to my blog, so I know that it's there. I can tell others are looking at it. But I can't see it.

Well, the good news is you don't have a blog hijack or other calamity. Your blog is not gone.

Apparently, some ISPs are blocking *.blogspot.com, or maybe have network configuration or infrastructure problems. You can access Blogger.com or you can access Blogspot.com, but you can't access nitecruzr.blogspot.com, or bloggerstatusforreal.blogspot.com.

You can't access them directly, that is. If you can access any free, anonymous proxy servers, though, you may be able to access your blog.

Note: You can use PKBlogs with the URL pre packaged. Here is the address of this post (with gratuitous line breaks to prevent the old post sidebar alignment problem):
http://www.pkblogs.com/bloggerstatusforreal.blogspot.com/

And an additional URL, to provide to those suffering from this problem, would be the WordPress version of this post:
