Coinbase’s Layer 2 network, Base, went down twice in the span of 24 hours this week, with block production grinding to a halt on both June 25 and June 26. The timing could not have been worse: the outages forced a postponement of the Beryl hard fork and its marquee feature, the B20 Activation Registry.
No user funds were reported at risk during either incident.
What happened
The first outage hit at approximately 16:03 UTC on June 25, triggered by a consensus failure linked to an invalid block sequence detected after block height 47,806,542. Block production remained stalled for roughly two hours before the team restored operations.
Then it happened again. Around 15:34 UTC on June 26, a second halt struck with what appears to be a similar root cause. Recovery followed a comparable timeline, with blocks resuming shortly afterward. The development team has said it is actively investigating both incidents and preparing post-mortem analyses.
