For the testing of a new traffic management tool there was an entry on the recently renewed stackstatus.net. I remember clearly because I asked about that posting in my answer here.
Looking back today the entry is no longer visible at the home-page, which is fine as the first step of the test was completed. However there is also no entry of this in the incident history.
What is the current guideline in place to deal with maintenance notifications that have "expired"?
