Our Engineers have implemented a fix which resolved the issue of thumbnails not loading on Projects and Boards. We can confirm that the service is now fully restored and that all new thumbnails should appear. However, older thumbnails with broken thumbnails will have to be re-uploaded. We apologize for the troubles this has caused!
