Polygon Briefly Goes Dark After Sudden ‘Validator Exit’ - Unchained
Polygon suffered an outage on Wednesday, when its Heimdall V2 consensus layer went down for about one hour, just weeks after a complex hard fork upgrade.
In an X post that has since been deleted, Polygon said the outage was triggered by an unidentified validator’s unexpected exit from the network, which led to a consensus bug in Heimdall V2.
Despite the outage, Polygon’s transaction layer Bor, which handles block production and transaction processing, remained fully operational, meaning regular transactions continued and the broader network was not brought to a complete halt.

Still, some users and developers experienced disruptions with block explorers and Remote Procedure Call (RPC) endpoints, notably with Polygonscan showing no new blocks during the outage
RPC endpoints are network addresses that users, wallets, or applications use to interact with the blockchain.
Around ten hours after the outage was reported, Polygon said in another X update that almost every RPC provider was back online, while noting that providers might still experience “degraded performance.”
