Custom Domain Publishing, And Google Apps - October, 2008

When you setup a Google Custom Domain, either using the "Buy A Domain For Your Blog" wizard, or using Google Apps manually, you'll get a complement of 4 DNS records defining the domain. 3 "A" records will define the primary domain ("root") by IP address, and one "CNAME" record will define the "www" alias by server name ("ghs.google.com"). This has been the standard since Google Apps started being used to setup the DNS for custom domains.

Here's the setup for my latest custom domain, "nitecruzr-test.net", as of 12 October, 2008.

nitecruzr-test.net. 3600 IN A 64.233.179.121
nitecruzr-test.net. 3600 IN A 66.249.81.121
nitecruzr-test.net. 3600 IN A 72.14.207.121
www.nitecruzr.net. 3600 IN CNAME ghs.google.com.


Recently, some bloggers have been seeing unstable DNS performance. One blogger, of unknown background, has "authoritatively" stated that
66.249.81.121 is gone forever. Removing that A record will help.


We can't verify the latter claim, but we can examine the current status.

It does look like the server in question is out of service, at least right now. A brief examination of the Google Apps forum provides no useful details.

(Update 10/13): A very authoritative source has confirmed that "66.249.81.121" is out of service, permanently. A new configuration is pending, and for right now, I will go with 2 servers. I recommend that you do the same, if you're able to change your DNS setup.

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.
