A Dutch CA called DigiNotar has suffered a security breach. Mozilla is removing trust from their root certificate – we hope to release updates today. We have used the EFF SSL Observatory data to make a list of affected websites (those whose certificates chain up to the DigiNotar root). We want to warn the webmasters of these sites that they need to get new certificates ASAP. And that’s where we use the power of the community :-)
If you can read Dutch, we would appreciate your help. There is a Google Docs spreadsheet with the list of affected sites and instructions on how to find the webmaster email or contact form and warn them, using a letter we have written. The more warning they get, the less disrupted the Dutch SSL internet will be. Please head over there and help out :-) Thanks!
 This is not the same as being issued by DigiNotar. Please do not contact sites not on our list.
