Description

Description

Improve the eth1 failover mechanic so that failover occurs when primary eth1 is reachable, but not synced to head

Primary eth1 may not fail entirely, and instead just fail to keep up with head

No files, tests, or entry points are named. Locate the eth1 failover mechanism and the logic that determines whether the primary is synced to head; done means failover occurs when the primary remains reachable but falls behind, with coverage for that condition.
