Dashboard Widgets/Reports Issue

All of my dashboards just went down at once. I have multiple across different departments that I built, they all run off of different reports and sheets. Oddly two of my older reports are still visible/functioning. This is not the first time this has happened, and when i go to edit, its prompting me to add data as if it somehow detached all the pre-existing data that I had set up. Is anyone else having this same issue or any tips on resolving this?
