Custom Domains And New Google Apps DNS Servers

We've been getting a lot of reports of some well known problems recently, from blogs published to Google Custom Domains.
Another blog is already hosted at this address.
and
Server Not Found

Error 404
No, Chuck, tell us something that we didn't know.

When I analyse a custom domain problem, I always start with a DNS analysis, expressed using an excerpted Dig log. Typically, I'll see
Symmetrical Main Domain

mydomain.com. 900 IN CNAME ghs.google.com.
www.mydomain.com. 900 IN CNAME ghs.google.com.

or
Asymmetrical Main Domain (aka "Google Apps" configuration)

mydomain.com. 3600 IN A 64.233.179.121
mydomain.com. 3600 IN A 72.14.207.121
www.mydomain.com. 900 IN CNAME ghs.google.com.


This weekend, though, we're seeing a variant on the latter configuration, reported as usual in anxious queries
For 3 days I received a message that the blog was redirecting. Then I got error 404 for a day and decided to switch to blogspot and back to my custom domain. Got an error that this domain is in use by another blog!!!!!!.


mydomain.com. 1800 IN A 216.239.32.21
mydomain.com. 1800 IN A 216.239.34.21
mydomain.com. 1800 IN A 216.239.36.21
mydomain.com. 1800 IN A 216.239.38.21
www.mydomain.com. 1800 IN CNAME ghs.google.com.

The "216" series IP addresses are the New Google Apps Engine DNS servers. They were supposedly deployed in custom domains to solve the ongoing "Another Blog ..." and "Server Not Found ...." errors. Apparently, even they are not immune to the problem. They are probably just as subject to random factors, like Time To Live variances, as the former Google Apps servers.

It looks like the Custom Domain Reset Form isn't going to be retired any time soon.

(Update 12/12): It appears that, though not officially published, the new servers are being used, in service.

I believe that this is precisely what is happening to my web page. Your blog is extremely informative and I am so happy to have found it, however, my problem is, I have no idea where to find my DNS settings let alone, change them...I purchased www.ShermanTheDog.net thru my google blog, www.shermanthedog-polit.blogspot.com. I am lost when it comes to all of this sort of stuff. I can tailor a man's suit , but this .... this is a foreign language that I don't speak. Thanks , Janet

Custom Domain Migration - Managing The Traffic

Your blog depends upon traffic for its success.

Anything that affects the traffic to your blog, such as any change in the URL, affects the success of your blog. Publishing the blog to a custom domain, like renaming the blog, will affect traffic to your blog. The effects of the change will vary from blog to blog, because of the different traffic to every different blog.Followers. People who find your blog because of recommendations by other people.Search engines. Robotic processes which methodically surf your blog, and provide dynamic indexing to people who search for information.Subscribers. People who read your content from their newsfeed reader, such as the dashboard Reading List.Viewers. People who read your content from their browser.No two blogs are the same - and no two blogs will have the same combinations of traffic sources.

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.
