"This morning, we made a code push that incorrectly flagged a small percentage of Google Docs as abusive, which caused those documents to be automatically blocked. A fix is in place and all users should have full access to their docs. Protecting users from viruses, malware, and other abusive content is central to user safety. We apologize for the disruption and will put processes in place to prevent this from happening again."
Translation: We floated a new filter in our scanning software and it worked as designed. We didn't actually expect you to go on social media and complain. How rude. We'll back off for now, but this is the future Google wants. Get used to it.
