The Mouse Connectivity Atlas at [https://connectivity.brain-map.org/](https://connectivity.brain-map.org/) is currently not loading properly. It only shows a blank page with a dash line (no interface, no errors, just empty).

- This has been ongoing for at least 2 days.

- Tried multiple browsers (Chrome, Firefox), cleared cache, different networks, no VPN issues.
- No official announcement about maintenance.

Is this a known issue? Any ETA for fix?

Thanks!

This is a known issue ([here](https://community.brain-map.org/t/allen-brain-connectivity-atlast-not-accessible/4751/2), [here](https://community.brain-map.org/t/mouse-brain-connectivity-atlas-down/4750/2)). Unfortunately, no ETA, but the team is working on getting it back up. Thank you for your patience!
