Cloudflare Research: Carrier-Grade NAT Users Face Higher Risk of Internet Throttling

Plain bagel done well. Pleasantly substantive.
Summary
Cloudflare research reveals that users connecting through carrier-grade NAT (network address translation) are more likely to experience internet throttling or blocking. This stems from historical IPv4 address allocation disparities, where early-adopting nations secured large address blocks, leaving others to rely on NAT solutions. When ISPs detect malicious traffic from NAT-shared IP addresses, they often throttle all users sharing that address, affecting innocent users along with bad actors.
