What is q4cdn? I did a whois, and I tried to find more details. I'm not sure why this wouldn't be directly from a Facebook IR or news wire hosted press release. I'd like to have some knowledge of who/what is running it, since this is a pdf.
https://www.q4inc.com/products/surveillance/default.aspx is a bit disturbing, but I can understand why it sells.
I'm still curious, but less concerned. They appear to use Cloudflare, AWS for DNS, and registered through Godaddy. I just haven't figured out who runs it. I wouldn't be surprised if it if were via business wire, but I'm surprised it's hard to find out. Multiple companys' IR teams seem to use it based on some cursory querying.
