Producing a TraceRt Log For Analysis

Many network problems that affect your use of Blogger, such as the currently obnoxious "Server Error 1-500", can be diagnosed, if we can understand how you are connecting to Blogger. A TraceRoute log shows us the path that your connection takes to a given server, and is very useful in this case.

On most systems, TraceRoute is run as "tracert". Here we have a tracert targeting "www.google.com". Choose your target according to your need.
  1. Open a command window.
  2. Type "tracert www.google.com >c:\tracert.txt" (less the "") at the command prompt.
  3. Type "notepad c:\tracert.txt" (less the "") at the command prompt.
  4. Copy, and paste, the entire log, as displayed in Notepad, into your email or forum post. Please don't munge, or disguise, any details.
It really is simple - when you know how. Just be generous - and precise (see the spaces in the commands?).

Here's a sample log.

C:\>tracert www.google.com

Trace complete.

You have two classes of information there. The list of IP addresses are very important, to understand the path that your traffic may take, between your computer and the Google server. The timings (or lack of them, as in "Request timed out") are not so important.

In many cases, a router (represented by one of the IP addresses in the list), though it will identify itself in the list, will prevent you from probing it for a timed response. The error "Request timed out" won't be as significant as the IP addresses.

See hops 10 - 12, highlighted above? Those represent routers operated by Singnet ("Singtel"), which are the suspected cause of the problems when this article was originally written.

If your computer runs a current version of Microsoft Windows, you may be able to run an improved equivalent of "TraceRoute", known as "PathPing", which produces a better organised log.

What's The URL Of My Blog?

We see the plea for help, periodically I need the URL of my blog, so I can give it to my friends. Help! Who's buried in Grant's Tomb, after all? No Chuck, be polite. OK, OK. The title of this blog is "The Real Blogger Status", and the title of this post is "What's The URL Of My Blog?".

Where's The Dashboard?

We see this confusion, a couple times a week, in Blogger Help Forum: How Do I? . Where is the dashboard? In the Classic Blogger GUI, the display which contained the "Blog List" (at the top), and the "Reading List" (at the bottom) was labeled "Dashboard". Many people also called the "Settings" / "Template" screens for the various blogs, linked from the Blog List, the dashboard. The New Blogger GUI has no page with the label - and no links "To The Dashboard". The Navbar (another unlabeled feature) has two links - "Design" and "New Post" - which lead to different dashboard sections, when you are appropriately logged in to Blogger . And, the "B" logo at the far left of the navbar will, similarly, take you to the Blog List / Reading List.
