All 6 snapshots fetched with HTTP 200. Read source-0.html.gz (CNCF announcement), source-1.html.gz (DBTA), source-2.html.gz (CNCF projects page), source-3.html.gz (The Stack), source-4.html.gz (Virtualization Review), source-5.html.gz (opentelemetry.io blog). The three sources flagged as not in allowlist — thestack.technology, virtualizationreview.com, opentelemetry.io — are all credible: The Stack is a reputable UK enterprise tech outlet, Virtualization Review is an established trade publication, and opentelemetry.io is the project's own official blog. The allowlist gap is a process issue, not a credibility or accuracy concern.
