  "notes": "OpenAI's blog post could not be opened (HTTP 403). OpenAI had earlier said it had notified 'dozens' of organisations. According to OpenAI, a notification does not mean private information was accessed or a system compromised. The brief cites the Washington Post; that article was not opened.",
