The issue has been identified and resolved. A crashed database denied access to our Advertising infrastructure. No data should have been lost.
We apologize for the inconvenience this may have caused to you. We will continue to research how this could have been prevented in the first place and revise our processes around this.
If you still occur any issues with Advertising log in please reach out via the chat in the down right corner of the tool or via firstname.lastname@example.org
