We lost Access to all our data in a project

[Will Hunt]

We suddenly lost all visibility to see charts, swimlanes, backlog, everything. This is over multiple browsers, multiple users, multiple machines. All other projects are okay and there have been no changes by Admins, etc. Help.

Is this Cloud or Server?

If it is Server, then check the logs - look specifically for user directory errors

Also sounds like it might be indexing problem.  Commonly reported as data is missing, but in fact the data still exists in the database, you might just need to rebuild the indexes to be able to see it again in the web browser.   But depending on which platform is in use here (Server vs Cloud) will determine the next steps to follow.
