Several nodes in our primary fleet have successfully resynced and are now serving traffic. However, we are not yet back to full capacity; customers may experience elevated latency or an intermittent error rate. We will provide a final update once all nodes are fully back online
monitoring
Our Sonic mainnet RPC nodes are continuing to resync from the latest snapshot. During this process, all traffic is being routed through secondary infrastructure with updated binaries. Websocket connections are unavailable until the resync is complete, and customers may experience elevated latency or intermittent errors on RPC requests. We expect the resync to finish within the next several hours and will provide another update once primary nodes are back online and operating at full capacity.

Nodes running older client versions fell out of consensus at block 66,026,364, while the network itself continued producing blocks normally. Our Sonic mainnet RPC nodes were affected. We have upgraded all nodes to v2.1.6 and initiated a full database resync from the latest snapshot. In the interim,...
