Cloudflare probably. The wins use cloudflare, even though they oughtn't

cloudflare has a penchant for blocking legit users and autologging out vpn users.

It's probably up to MUCH worse things like 'cloud keylogging' (recording every keypress as you create comments / posts, and sending them to another server; probably fbi, nsa btw or signature reduction)

Probably also doing extreme fingerprinting of your browser well beyond browscap; and selling to others

Prob doing all sorts of google-tier nefariousness

The wins should get their own OSS cdn antiddos technology

(there are open source self hosted anti ddos clouds one can use but you'd have to get multiple vps instances)
