The Polygon Heimdall V2 mainnet experienced a temporary outage due to a suspected consensus bug, with service restored shortly after. The downtime occurred around 9:30 UTC and was attributed to the exit of an unidentified validator from the network. Importantly, the Bor layer, responsible for transaction execution and block production, functioned without interruption. Polygon's spokespersons have confirmed that block explorers are now re-synced, and discrepancies between network uptime and explorer data are being addressed. They are collaborating with RPC partners to ensure full restoration, with one provider already back online. The recent upgrade in early July enhanced the network's tech stack but introduced complexity that could lead to more vulnerabilities. Historically, previous issues with Heimdall V1 in March 2022 were also linked to similar bugs.
