Internet infrastructureWhat's changing
Impersonation infrastructure appears in bursts, not at a steady rate
Across 21 days the busiest carried 265 detections against a typical 41 — a campaign stands up many domains at once, so a quiet week says little about the next one.
Google and Microsoft run 25.3% of mail-operating domains with a named provider
Share of mail-operating domains with a named provider, by mailbox provider: the registrable domain of each domain's primary MX, matched against the provider catalog.
57.6% of prefix announcements carry no signed origin claim
Whether a published ROA covers each announced prefix, and whether it agrees with the origin.

For corporate domains, the correlated exposure is the registrar-and-hosting bundle, not the CDN: one in five get DNS, website and mail from one company, and two in five in Germany.
