In response to the long-term data non-update of the blockchain browser PolygonScan in the early morning of this morning, Polygon officials said on Twitter that around 4:26 am, some nodes lost synchronization, which caused some nodes to be unable to verify the block response for a short period of time. Block production has never stopped, however, network performance may have temporarily decreased. At present, the nodes have been resynchronized and the system has returned to normal. According to PANews, the data on PolygonScan has now returned to normal.

In addition, according to CoinDesk, Greg Lang of Rivet, a node infrastructure provider on Polygon, said that Polygon's problem seemed to stem from an "abnormally large" block reorganization, which occurred two minutes before Polygon said the node lost synchronization. Lang said that small-scale block reorganizations are common on Polygon and other Ethereum Virtual Machine (EVM)-based networks, and they do not necessarily cause concern, but the difference this time is the scale of the reorganization, which is 157 blocks.
