Mousing over events gives all of the details available such as how long, where and with whom the event was along with hops and so on.

In the historical outages and average times of outages feature, users can select a certain date range which gives an overall view of outages over that period of time. When selecting a range such as one week, one month and so on, all outages for that period will be shown along with average outages times for the same period of time.

The default historical view is one week. If not data shows, try changing the range to two weeks, a month and so on.
