Monitoring

We’ve implemented multiple mitigations on our side (restored archival capacity, improved peer stability, and more).
Error rates have dropped dramatically and the service is stable. We’re continuing to work with the Polygon team on the remaining client-side syncing/peering hardening; very rare isolated occurrences may still be observed in the short term.

Investigating

The Erigon segment of our Polygon Mainnet node fleet is experiencing synchronization issues. This may result in elevated 32xxx errors for requests that depend on historical state. Our team is actively applying corrective measures and coordinating directly with the Polygon team to accelerate full remediation.
