The key thing to take note of, is deviations from normal latency baselines.
TIP: Items in Alphabetical order, DNS IP servers @ the top. If you want to change the default time slice duration from 5min to lets say... 1hr, 6hr, 12hr or even 30 days for historical trends. Click the Clock symbol down arrow and select time frame.
