Google accidentally blocked some people from accessing their files on the company’s Google Docs service Tuesday, a spokesperson said.

“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,” the Google spokesperson said in a statement. “A fix is in place and all users should have full access to their docs.”

Throughout the day, journalists, students and other users expressed frustration on Twitter at not being able to access their files. Some said they were told that the documents violated Google’s terms of service.

The Google spokesperson said protecting users from viruses, malware and other abusive content was “central to user safety.”

“We apologize for the disruption and will put processes in place to prevent this from happening again,” the spokesperson said.
