Identified

We have identified the root cause of the zkEVM mainnet block height stall in the EU region. The issue is related to a brief internal Erigon update that triggered an automatic unwind process. The system will recover automatically once the unwind completes and syncing resumes. Recovery time is dependent on node processing capacity in the region, with no exact ETA available at this time.

We expect to provide an update by 15:00 UTC, 28 August.
