Network partition
Timeline · 1 update
- resolved Jun 25, 2026, 08:10 PM UTC
From 13:26–14:14 UTC there was an incident involving transaction landing and Laserstream streaming, during which some users may have seen failures to land transactions and/or lag in Laserstream. This was caused by a Solana network partition at an epoch boundary, where a validator forked off and began emitting broken shreds. As a result, some parts of the network observed the issue while others did not.
