Base mainnet outage triggered by anomalous block; network operations restored

ChainCatcher reports that Base said at 00:27 Beijing time its mainnet suffered an outage after block production ran into issues. The team attributed the disruption to an anomalous block that interfered with subsequent block construction, adding that user funds remained safe. At 01:53, Base said new block ordering had been restored and internal nodes were syncing normally. Operators running validator nodes were instructed to restart their Base nodes to resume synchronization. By 03:22, Base reported block production had returned to normal, with applications and infrastructure gradually coming back online as nodes restarted. The team said it has identified the root cause and will prioritize publishing a full postmortem. Separately, The Block noted the incident occurred on the same day Base had scheduled its Beryl upgrade for 02:00 Beijing time, though the outage was reported to be unrelated to the planned maintenance.
