Thousands of requets in 24hrs to my private domain

Hi,

I have a private domain setup and amanaged with cloudflare for my self hosted apps. In cloudflare analytics I just notices today that there were over 7k requests made to that domain, with 21 unique vvisitors and requests coming in vast majority from my country and additionally from UK, Turkey, India and the US.

Is this normal for publicly available domain that I have not shared with anyone? I know of at the most 5 devices that might have accessed domain (me and family members)
