My manager and I just lost all progress in some of our notebooks. I had a notebook that I had been working on for about 2 weeks and had no issue saving. About two hours ago the notebook disconnected. I refreshed the page and found the code had been replaced with the standard two lines of code you get when you create a new notebook.
My manager found the same issue with one of her notebooks. We're checking to see if any other notebooks are affected. The names, ID's and files associated with the notebooks are all unchanged.
Has anyone run into this issue before? Is there some archive we can access to recover lost scripts? I didn't expect this scripting environment to be this unstable.
