Traffic from service provided "cloudflare inc." in google analytics


I have a few websites that I use the free Cloudflare service. In one of these website’s google analytics, I see peaks of pageviews that are happening once/twice a month.
When investigating these peaks, all that traffic seems like it’s bot traffic.

  • Browser = Mozilla compatible agent
  • Language = c
  • Operating system = (not set)
  • City = (not set)
  • Service Provider = cloudflare inc.

Can anyone help me understand why this bot is accessing the website?
I don’t see this behavior in any of the other websites that use Cloudflare.
