Thanks for initiating this discussion ! To address the first part of why you are suddenly noticing DFS detections, its because we added DFS detection events into the Alert Hub and also on the AP details page on our dashboard earlier this month. These same DFS detection events were being captured in the event log all along and to raise awareness of potential impact of DFS hits, we decided to add this additional visibility. You can find additional details on this and potential actions to consider captured here: https://documentation.meraki.com/MR/Radio_Settings/Dynamic_Frequency_Selection_(DFS) . Do feel free to reach out if you have additional questions or any feedback you may have on this new visibility.
