ICSI Netalyzr leaves beta

Today we are taking the ICSI Netalyzr out of the beta stage. Among the changes we are rolling out are:
  • New tests. We now provide a path MTU test, IP fragmentation support, improved DNS examination, and look up additional names. Besides the client-side transcript you can now inspect the server-side one, which is useful for debugging highly troubled sessions. In addition, we have improved the overall robustness of the existing tests.
  • Interface improvements. A frequent complaint we received was that the results summary is overwhelming. As a first step to improve the situation, you can now selectively show or hide result summary detail. On the summary page, you find clickable plus/minus symbols that will expand/collapse test results on the entire page, in a particular test class, or on a particular test. When you first arrive at the summary page, any issues we have noticed remain expanded by default.
  • Updated info pages. Each of our tests comes with an info page, available by clicking on the test's name (such as "Path MTU" in the above). We have given those info pages a makeover, which will hopefully make them easier to understand and more useful to less technical users.
We hope you will enjoy the new Netalyzr. Many thanks to everyone who has tried out the tool in the past!
