Polygon’s proof‑of‑stake (PoS) web suffered a one‑hour outage connected July 30 that disrupted apps and users.
According to Polygon CEO and laminitis Sandeep Nailwal, the incident did not halt artifact production.
However, QuickNode Status reported that artifact accumulation stopped for 1 hr astatine artifact tallness 74,592,238, echoing other reports made by users connected X.
Consensus hiccup
In a station connected X, Nailwal said respective RPC providers “and hence corresponding apps and users” faced issues implicit a two‑to‑three‑hour window. At the aforesaid time, the concatenation “remained operational and continued to nutrient blocks and process idiosyncratic transactions” for unaffected RPCs.
Polygonscan information indicates that the web generated a caller block two seconds after artifact 74,592,238, arsenic of property time, contempt the artifact explorer displaying stalled artifact accumulation astatine this height.
Nailwal traced the incidental to a hotfix and a impermanent intermission connected the statement (Heimdall) furniture tied to a recent, analyzable upgrade. The execution furniture (Bor) continued running, but immoderate RPC nodes fell retired of sync aft the fix, creating app‑level failures that felt similar a web halt.
He apologized for the end‑user interaction and said Polygon is moving with providers “to bring everyone up to speed,” expecting nary further follow‑on issues.
Halted artifact production
Infrastructure operators described the aforesaid symptoms. QuickNode reported the mainnet stalled from its vantage constituent astatine artifact tallness 74,592,238 and warned that the new Heimdall v0.2.16 upgrade was causing issues with execution clients Bor and Erigon.
The institution paused upgrades “until further notice,” advised operators not to proceed, and began resyncing afloat nodes portion resetting Erigon instances to reconstruct service.
Polygon’s presumption page isolated the fault to the Heimdall‑V2 network. The squad said the mainnet Heimdall work became unresponsive, affecting validator and checkpoint visibility via Heimdall APIs, but emphasized determination was nary interaction connected the Bor layer.
Engineers identified the contented and deployed a hole earlier marking the incidental resolved.
The timeline shows however the disruption unfolded and dispersed crossed teams. Polygon opened the incidental astatine 09:52 UTC connected July 30, identified the contented by 09:57, and declared it resolved astatine 11:01.
QuickNode past reported a stall astatine 11:28, paused the Heimdall v0.2.16 rollout astatine 11:51 pending guidance from the Polygon Foundation, and by 15:39 said it was resyncing and resetting nodes to bring services backmost online.
Nailwal characterized the occurrence arsenic a coordination spread betwixt statement and infrastructure alternatively than a protocol failure.
The station Polygon suffers hour-long RPC disruption affecting artifact production; Heimdall hotfix to blame appeared archetypal connected CryptoSlate.
