A ✅ only means that the connection failed. Browsers do not tell the page why, so a network problem looks the same as a rejected certificate. To double-check, open the link in that row: if it loads without a warning page, the browser is vulnerable.
On 22nd October 2026, two chains marked No CT were added. Their leaf certificates were never logged to Certificate Transparency (CT), so clients that enforce CT reject them even if they still trust the intermediate. A successful connection to these hosts means the client trusts the compromised intermediates and does not enforce CT. These are the clients that can be attacked without anyone noticing.
