I received usage notification although no traffic

[Skywill]

Hi there,

I normally enabled Network usage alert over 1GB while 20 minutes.

But, the last few days I receive above notification by email while late night.

Then, office has no worker and traffic usage graph on home screen of Meraki Go App.

What does mean this events?

Should I suspect security problem such as unauthorized access?

I hope this is the bug...
