DataNose API
DataNose is the course, registration, timetable and thesis-administration system used by the University of Amsterdam's Faculty of Science. Its API host resolves into UVANET1, the university's own RIPE allocation, and its Swagger UI answers 200 — but the Swashbuckle discovery document it points at, /swagger/docs/v1, returns 500, so the machine-readable description of a genuinely institution-run course surface is currently broken. Recorded because it is real and institution-operated, and because the broken descriptor is the finding.
