Polygon Hemidall mainnet experiences temporary outage

Key Points

1. The Polygon Heimdall V2 mainnet, the consensus client for Polygon's proof-of-stake network, faced sync inconsistencies across several RPC providers’ Bor nodes after its recovery.

2. Block production on the Bor layer was not halted, and Polygon’s block explorers have re-synced and are displaying accurate data.

3. Polygon is collaborating with RPC partners to resolve the issues, with one provider already back online.

4. The Heimdall V2 upgrade, launched in early July, aimed to reduce finality times and was described as Polygon's most complex hard fork since its 2020 launch.

5. Heimdall V1 had previously caused network downtime issues, including a several-hour outage in March 2022.
