Learning objectives
- 01Instrument an L1 and build its dashboard
- 02Alert on production halts and divergence
- 03Carry out a coordinated upgrade
Guided lab
Instrument your L1, induce a production halt and verify the alert fires.

Carry out an upgrade across a multi-validator network with no service interruption.
Security angle
Validators on different versions: detect divergence before it becomes a fork.
Assessment
Dashboard, a fired alert and a documented upgrade.
