    The issue has been identified and a fix is being implemented.

  2. identified May 09, 2026, 07:40 AM UTC

    Subscan is currently conducting routine maintenance on historical block data. During this maintenance period, your user experience may be affected as follows: 1. You will temporarily be unable to view or search historical block data (including details of past blocks, historical transaction records, and other non-real-time block-related information); 2. Latest block data (such as real-time block information and latest transaction records) will remain unaffected, and you can view and access it normally. Once the maintenance is completed, the query function for historical block data will be automatically restored without requiring any additional actions from you. Any updates on the maintenance progress or special adjustments will be synced via the Subscan Status Page as soon as possible. We recommend you follow the page for the latest updates.
