At 8:58AM PST a backend update was released (Backend v16.0.4) which caused a brief disruption in the web vault. The DevOps team immediately reverted to the prior version 16.0.3 while remediating a newly-staged update.
This update contains several improvements and new features. Version 16.0.4 is being verified and will be published this week.
