Actually I had someone correct me after I wrote this email, we already have been doing that the whole time. > > Pointing *everyone* directly at Cloudflare might be expensive, if that > meant millions (or even thousands) of new clients. At least it would let us know how many users we have. Best I can tell on a given day, we have 2.5M users daily that hit us. Obviously the unique user count is much higher (as there are several users behind one NAT IP, and local mirrors and the like.). Our monthly numbers are north of 11M users, (as some people only run freshclam once a week or something like that.). I guess what I am trying to say is, it may not be that much more traffic. > > How does Cloudflare charge Talos for ClamAV?

Paul, how about you just point everything you have at us and see if it makes a difference?
