Incident Report

Summary AI Generated

Zapier's file storage domain (zapier-dev-files.s3.amazonaws.com) was flagged by Google Safe Browsing, causing browser-level security warnings or blocks when users attempted to open or download files hosted by Zapier, particularly through Forms and Tables. Multiple customers were unable to access file links, though Zaps continued to run normally and server-side file access was unaffected throughout the incident. Zapier's Security team identified and removed the flagged files, then coordinated with Google to have the dangerous site flag reviewed and lifted, with the domain remaining under the browser warning until Google completed its review.

We've completed the initial cleanup and are now collaborating with the Google team to determine the next steps needed to clear the "dangerous site" flag on our file storage domain.

During this period, your files that passed through Zapier remain safe, and Zaps, Tables, and Forms are functioning normally. Files passing through Zapier work normally on the system side as well. However, when opening a Zapier-hosted file link directly in your browser, you may still see the "dangerous site" warning until Google lifts the flag. We'll update this page as soon as we have news about when this flag will be removed.

We have received information from Google about the "dangerous site" flag on our file storage domain, and our Security team is now removing the files Google identified as dangerous to restore access.

Once this cleanup is complete, we will work with Google to have the flag reviewed and lifted. We will update this page as soon as there is progress.

Until then, you may still see a security warning when opening Zapier-hosted files in your browser. Zaps continue to run, and server-side file access isn't affected in the same way.

Our team is continuing to investigate the "dangerous site" flag when opening files hosted on Zapier storage while Chrome's Safe Browsing is enabled. We are awaiting confirmation from Google that the issue is remediated.

Users of Tables and Forms are the most likely to run into this, but it can happen anywhere a Zapier-hosted file is opened in the browser.

We'll continue to keep you up to date on our progress.
