➤ MEV Relay Outage by bloxRoute Labs Explained
On September 21, monitoring platform ethereumpool.info reported that 40% of Lido’s validators went offline, skipping over 8 block proposals in an hour. Other staking pools and operators faced similar issues.
Root Cause:
- The MEV relay service from bloxRoute Labs failed to return signed blocks, causing validator disconnections.
- The outage stemmed from an undetected bug during testing.
Response:
- bloxRoute Labs apologized and pledged to compensate affected validators for missed rewards.
- Teku developer Ben Edginton cautioned against normalizing outsourcing critical functions for profit.

➤ Why Solo-Stakers Underperform Post-Merge
Developer Somer Esat identified 6 key reasons:
- Insufficient hardware (RAM/CPU) for running execution layer clients.
- Low SSD performance (IOPS) for syncing execution and consensus clients.
- Client performance issues (e.g., undiscovered bugs).
- User errors (outdated software, misconfigurations).
- Lack of centralized support for troubleshooting.
