Current hosting and analytics

As of 23 October 2026 this publication is delivered through Cloudflare and independent temporary AWS hosting. Optional browser analytics uses Amazon CloudWatch RUM in our website hosting account to measure page views, document-link selections and approved navigation links. It sets no analytics cookies or browser-storage entries and uses no persistent visitor identifier. Temporary authorization and a document-session identifier exist only in memory. Collection stops when Global Privacy Control or Do Not Track is enabled; reading, search, themes and downloads still work. Events contain approved page and document identifiers and a limited referral category. They exclude search phrases, form contents, full referral URLs, URL queries and fragments, and recordings. AWS processes the network information needed to receive events and may derive approximate geographic information. Detailed browser events are private and expire after 30 days. Link selections do not establish completed downloads or reading.

Private delivery measurements contain HTTP status, transferred byte counts and request duration only. These records are limited to 30 days and a bounded storage allowance; daily aggregate counts are limited to 12 months. Cloudflare and AWS process the network information needed to deliver the website. Historical analytics in the former AWS account have not been migrated or recreated. The earlier hosting and analytics description below is retained as publication history; this notice describes current collection.

Rights and permissions¶

This collection is made available for reading and review. No open-source, Creative Commons, patent, implementation, or commercial-use license is granted by this notice. Permission to adapt, redistribute, or incorporate protected material into another publication, product, or system must be obtained from the rights holder unless the use is otherwise permitted by applicable law.

This notice does not remove rights supplied by applicable law or by the terms of a hosting platform. Public access is not a promise that copies can be prevented or recalled.

Third-party material identified in THIRD_PARTY_NOTICES.md retains its own license. This notice does not restrict rights granted by those licenses.

Permission requests may be sent to [email protected]. Do not include confidential information in a public request.

Publication analytics and privacy¶

This publication uses AWS Amplify hosting access logs to understand requests for research pages and documents, including identifiable crawler services. If browser analytics is enabled, Amazon CloudWatch RUM also measures page access and selections of research documents, internal reading links, and approved external links. A document selection does not establish successful delivery or reading.

Browser measurements contain only approved page and document identifiers, the publication edition, and referral or external host names. Search phrases, URL queries and fragments, form contents, clipboard contents and session recordings are excluded. Analytics creates no persistent cookies, visitor identifier or browser-storage entry. Temporary AWS authorization and an ephemeral document-session identifier exist only in memory. AWS receives the network information necessary to deliver its services and enriches private RUM records with approximate geographic information. This geographic information is excluded from the publication’s retained aggregates.

Browser collection respects Global Privacy Control and Do Not Track. It can be blocked using browser privacy controls without preventing reading or downloads. Ordinary hosting access logs remain subject to AWS hosting operation and best-effort delivery; their availability does not establish an individual's identity or a model's review.

The private analytics store retains hosting exports and detailed events for 30 days and aggregate counts for 12 months. AWS Amplify separately retains its original access logs while the hosting app exists. Administration and retained analytics are private. Contact Andrew Durden for privacy inquiries.
