I can see tiktok being more popular than apple, people watch videos much more often than they buy phones. But microsoft being more popular than tiktok? What's so popular on that site?
Every single Windows PC calling home to see what ad to play next or report on its user's metrics. Multiplied by whatever frequency that occurs.
If they're just using DNS lookups, probably windows update, telemetry, crash reports and other automated traffic.
Also, verizonmedia.com at 8th place? What's on that site? Some type of CDN?
Verizon Media afaik is EdgeCast or related, but I’m not 100% sure.
Cloudflare says they exclude "content servers"[1], I assume that means CDNs. https://www.verizonmedia.com/ says it is an ad network, including video ads, with brands like Yahoo, HuffPost and TechCrunch.
