Tiers: primary = twilio.com and www; critical = customer-facing or revenue names (login, account, store, marketing/brand, support, developer, downloads) on any owned domain; other = remaining public names (low weight); internal = dev/test/mail/VPN-looking names, excluded from share. "CDN & Security" is the front door a visitor connects to (CDN/WAF or the cloud load balancer). Grey rows did not resolve. Weight = share of the company's traffic-weighted total.
