[dns-operations] Oh, What a Fragile Web We Weave: Third-party Service Dependencies In

[Stephane Bortzmeyer]

Good paper, it seems, about dependencies of famous US Web sites (Alexa
top), including transitive dependencies (something which is typically
forgotten, see all the papers on the Dyn attack mentioning as victims
companies like AirBnb which did NOT use Dyn). Many measurements.

Executive summary: because of the concentration of providers, you can
take down a sizable part of Alexa by breaking only a few providers.
