Users of Yandex Disk have reported issues accessing files following an incident at the Sasovo data center on October 8. Some files show missing thumbnails, while others display thumbnails but fail to download, returning a 504 Gateway Time-out error.
Technical analysis using cURL indicates that requests to the storage server result in timeouts after approximately 10 minutes. The issue affects both the photo gallery and general file storage sections of the service.
As of October 10, one user reported that approximately 1 percent of their stored data, totaling about 21 GB out of 1.9 TB, remained inaccessible. Yandex support has not provided an official explanation regarding the cause of these access errors.
