HA Ledger Split-Brain Prevention Rules
Prevent HA ledger split-brain with quorum, fencing tokens, and Protocol 201.3 write-authority rules that survive regional partitions and false failovers.
|
Two primaries means two truths
High-availability ledgers fail dangerously when network partitions allow two regions to accept Protocol 201.3 writes. Split-brain prevention needs quorum, fencing, and a single write authority—not hope that async replication catches up.
globalserverbank is not a licensed bank. Patterns complement high-availability ledgers and disaster recovery.
Control-plane notes often ship with Global Server Protocol deployment guidance.
Quorum, fencing, and write authority
Require majority quorum (or equivalent) before promoting a posting primary. Issue fencing tokens so a stale primary cannot write after demotion. Protocol 201.3 services must refuse posts without holding the token.
Test partition scenarios that look like successful failover but leave the old primary alive. Measure RPO/RTO honestly under those tests.
Hosting topology
Place ledger nodes on isolated cloud banking server regions with documented latency and witness placement. Avoid stretch clusters that violate quorum assumptions.

Frequently asked questions
Is multi-AZ the same as split-brain safe?
No. Availability zones help, but without fencing and quorum you can still dual-write during partitions.
Can read replicas accept Protocol 201.3 posts?
No. Only the fenced write authority should accept monetary posts.
Does globalserverbank host production ledgers?
No. It publishes architecture intelligence; hosting patterns reference cloudglobalserver.com as ecosystem infrastructure.
