Polygon outage: causes and consequences

The developers explained that the temporary failures were caused by technical work on Polygonscan, due to which incorrect data was displayed, journalist Colin Wu reports.
For several hours, the community expressed dissatisfaction with the lack of official comments from the project team. In response to questions and complaints, Polygon Labs said that the problem arose due to a failure in Heimdall, a network component responsible for verifying transactions and synchronizing with Ethereum. One of the validators unexpectedly exited, which led to a stop in the creation of new blocks for one hour.
The official message from the Polygon Foundation notes: about four hours ago, Heimdall encountered a temporary failure caused by the exit of a validator, which caused the chain to pause for an hour. At the same time, Bor, the mechanism that generates blocks, continued to operate without interruption. The company's engineers responded quickly, fixing the problem within an hour and restoring Heimdall to normal operation.
Polygon Labs also reported that the Heimdall outage may have temporarily caused problems with data synchronization on Polygonscan, but Bor continued to create blocks as usual. The team is currently working with RPC providers to speed up the full restoration of the network.
The price of the MATIC token fell by about 5% against the backdrop of the incident, according to CoinGecko. As of the time of publication of the article, the cryptocurrency was worth about $ 0.21.
It is worth recalling that this is not the first case of technical problems in the Polygon network. Earlier, on March 23, 2025, a large-scale failure occurred on the Polygon zkEVM second-level platform, due to which the blockchain remained unavailable for more than 10 hours.
Incidents like these highlight the importance of infrastructure stability for decentralized networks to operate and impact user and investor confidence. Polygon continues to work to improve its platform to minimize the risk of similar outages in the future.
