Diagnosing Geographical Location / IP Address

We see various problems reported, in Blogger Help Forum: Get Help with an Issue , which may involve geographical or network relationships. Why can't I regain access to my blog, that I stopped publishing 5 years ago? and Why can't I see my blog? and Why does my dashboard show up in a language that I can't read? With questions like these, it helps to know how and where the owner and / or readers of the blog get Internet service.

Effectively Testing Reader Access To Your Blog

People reporting a problem with blog access / performance, in Blogger Help Forum: Get Help with an Issue , will be frequently advised to diagnose their problems using affinity / differential testing . Some diagnostic advice starts with simple instructions to " clear cache, cookies, and sessions ". Some people, alternately, advise "use a different browser" - and test as a reader. These different strategies, seemingly redundant, will frequently lead to different results.

Blogger Magic - Using An HTTP Trace

An HTTP trace is a very useful tool, for diagnosing and documenting connectivity issues, and many other blog problems. I use the Rex Swain HTTP Viewer , for this purpose. HTTP Viewer lets you package a given display, in the URL, so you can give simple instructions (accompanied by an unavoidably complicated link): Click on the link: http://www.rexswain.com/cgi-bin/httpview.cgi?url=http://klarfamilylife.blogspot.com&uag=Mozilla/5.0+(X11%3B+CrOS+armv7l+7834.70.0)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/49.0.2623.112+Safari/537.36&ref=http://www.rexswain.com/httpview.html&aen=&req=GET&ver=1.1&fmt=AUTO And when the link is clicked, the necessary HTTP trace is displayed. There is no need to provide instructions how to actually enter the necessary values, on the HTTP Viewer home page, to generate the necessary display.

Various Problems With Blog Owners Using Internet Explorer V11

We're seeing a few browser related problems, possibly related to a recent update of Microsoft Windows and Internet Explorer, reported in Blogger Help Forum: Something Is Broken . I can't see my dashboard! and I can't upload pictures - all that I get is a blank box! and I am receiving messages, when I log in, that my Internet Explorer is not compatible with Blogger. Too many blog owners use Internet Explorer for using Blogger - and automatically accept updates, applied by Windows Update. Right now, Blogger Engineering is in the process of updating Blogger to work with Internet Explorer V11. This is not a minor task - with all of the many Blogger features required by the various blog owners and readers, all of which must be checked for compatibility with each new browser version .

Diagnose Problems Using Differential Testing

Sometimes, you may find yourself reporting a problem, in Blogger Help Forum: Something Is Broken - and observe that nobody else has the same problem. If there's any normal problem activity in the forum, you might find yourself waiting - in vain - for an immediate answer to your problem report. While you wait for advice, why not do some basic analysis of your problem? A differential test set of your problem, based on some reasonably basic details, can help you see where many problems may originate.

Diagnosing Problems With Your Blogger Connectivity

One of the most frustrating problems reported occasionally in in BHF: Something Is Broken comes in very terse langauge. I can't access my blog. or slightly longer I can't access any blogs .or possibly I can't access Blogger. In situations where the blog owner, and / or any number of blog readers, are cooperative, and able to take a few minutes to perform some simple tests, we can conduct a Affinity based analysis - or possibly an Affinity / Differential Analysis.
