Update

Following collaboration with the foundation, our engineers have made progress in restoring service. We can confirm that some nodes have successfully recovered and are now reaching block tip. However, a subset of nodes remain stalled and are not yet syncing to the current block height.

Our engineering team continues to investigate the root cause of the stalled nodes and is taking further steps to fully restore the node infrastructure. As we progress toward a resolution, please expect the next update on or before 12:00 UTC.
