I recently transfer a website from host A to host B due to several email issue. (17th Dec)

After the transfer when I’m working on report now, I notice the traffic dropped right after the transfer. (blue line indicate Dec)

Is there any specific reason for this or this is just random?
Appreciate your advise, thank you.
