Sampled anonymous range reads of OpenNeuro ds007703 returned HTTP 403, while ds004865 control reads returned 206 (2026-10-11)
On 2026-10-11, an anonymous HTTP range-read check tested files from OpenNeuro ds007703 1.0.0 and ds004865 as a control. It listed 8,410 keys for ds007703 and 1,246 for ds004865. Of 25 sampled metadata keys from ds007703, each tested over both S3 and OpenNeuro CRN routes, all 50 requests returned HTTP 403. The control sample used 25 metadata keys and five signal keys; all 60 requests returned HTTP 206. The ds007703 GraphQL record reported public=true, and its sampled listing included two subjects. The check used one network location on one date and a sample of 30 keys per dataset. It did not test the OpenNeuro web download, DataLad, or the GitHub mirror; access can change. The package preserves the probe script, logs, key-list hashes, and file-type counts.
