Today, Google’s Chrome browser blocked access to Dutch news website Nu.nl. At first it did so when visiting specific URLs:

Problematic URL:
http://www.nu.nl/buitenland/2851974/wikileaks-publiceert-syrie-documenten.html
The diagnostic page Google refers to wasn’t particularly helpful at first…

But moments later, this changed into:

Making note of problems observed a day ago (4th July), but which were not being reported by Google until later today (5th July), only after the news site was already being blocked by Chrome.
Also, earlier today (5th July) Google did not indicate any malware issues when visiting other URLs leading to this domain. Later on, more and more URLs leading to this domain would be blocked.
