Validator Incident Response Playbook

Validator downtime can quickly escalate into missed blocks, jail events, and potential slashing depending on chain rules. Fast response and disciplined operational procedures are essential for maintaining validator uptime and delegator trust.

This guide outlines the practical response workflow when validator alerts indicate a potential issue.

Operators commonly rely on monitoring systems to detect validator health issues quickly. FoxxOne Validator Alerts provides Telegram notifications for missed blocks, jailed status, governance proposals, and stake movement events.

Validator Incident Response Guide

Structured response flow for live operational incidents.

Preventing Validator Incidents

Most validator incidents come from predictable operational faults. Baseline prevention should include:

Maintaining healthy peer connectivity.
Monitoring node sync status and block-height drift.
Tracking missed block counters continuously.
Ensuring signer process stability and key access health.
Maintaining validator infrastructure alerts as a first-line signal.

Runbook Workflow

Detection

Missed blocks or jailed validator alerts are usually the first indicator of an operational issue.

Immediate Response

Acknowledge the alert and record a timestamp.
Confirm if the issue is local (your stack) or chain-wide.
Pause non-essential maintenance until validator health stabilizes.

Diagnosis

Check node logs for consensus/signing/runtime errors.
Check sync state and block-height movement.
Check peer connectivity and network latency.
Check signer process, key access, and service state.

Recovery

Restart services only after cause is identified.
If jailed, execute chain-specific unjail flow only when fully synced.
Monitor block signing recovery and missed-block trend.

Post-Incident Review

Document the incident and timeline in your ops log.
Update your runbook with the exact remediation sequence.
Adjust monitoring thresholds or alert routing where needed.

Terminal Runbook (Infinite Chain)

These commands help validator operators verify node health and recover from a jailed state quickly. Commands assume Drive deployment defaults.

Chain ID: infinite_421018-1
Service directory: ~/drive/services/node0-infinite
Run commands from this directory unless noted.

Verify Node Sync Status

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited status | jq '.sync_info'

Critical check: catching_up must be false. If true, do not attempt unjail.

Quick Sync Check

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited status | jq -r '.sync_info.catching_up'

Expected output: false

Alert-Specific Quick Checks

These checks map directly to key alert types and avoid duplicating the sync/unjail steps above.

Missed Blocks Signal

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited q slashing signing-infos --limit 200 | jq

Governance Voting Window

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited q gov proposals --status voting_period | jq

Delegation / Stake Movement Baseline

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited q staking validator YOUR_VALOPER_ADDRESS | jq '.tokens,.delegator_shares'

Validator Jailed Recovery (Step-by-Step)

Validator Jailed Recovery

Do not unjail until the node is fully synced and the root cause has been addressed.

Step 1 - Confirm Node Is Synced

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited status | jq -r '.sync_info.catching_up'

Only continue if output is false.

Step 2 - Check Current Jailed State (Optional but Recommended)

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited q staking validator YOUR_VALOPER_ADDRESS | jq '.jailed'

Step 3 - Execute Unjail Transaction

--from uses the local key name stored in the node keyring, not the wallet address.

To view your wallet name in keyring:

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited keys list --keyring-backend os

Use the name shown in output for --from. Example: validator.

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited tx slashing unjail \
  --from validator \
  --chain-id infinite_421018-1 \
  --keyring-backend os \
  --gas auto \
  --gas-adjustment 1.3 \
  --fees 5000drop \
  -y

Step 4 - Confirm Validator Is Active

Replace YOUR_VALOPER_ADDRESS with your validator operator address (example: infinitevaloper1xxxxxxxxxxxxxxxxxxxxxxxxxxxx).

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited q staking validator YOUR_VALOPER_ADDRESS

Confirm output includes "jailed": false.

Check Current Block Height

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited status | jq -r '.sync_info.latest_block_height'

Check Latest Block Time

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited status | jq -r '.sync_info.latest_block_time'

Confirm Chain ID

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited status | jq -r '.node_info.network'

Expected output: infinite_421018-1

cd ~/drive/services/node0-infinite
./drive.sh exec infinite infinited status | jq '.validator_info'

Node Troubleshooting

View node logs:

cd ~/drive/services/node0-infinite
./drive.sh node-logs

Restart node if process is unstable or unresponsive:

cd ~/drive/services/node0-infinite
./drive.sh node-restart

Operational Guidance

Unjailing without fixing root cause leads to repeated jail cycles and higher slashing risk. Common causes include sync lag, peer/network issues, process crashes, and server resource exhaustion. After recovery, monitor signing behavior and missed-block trend for several block windows.

Why Rapid Response Matters

Missing blocks for extended periods can lead to validator jail. Repeated incidents can result in delegator withdrawals and reduced validator reputation. Monitoring and fast operational response help minimize downtime and protect stake participation.

Operational Monitoring

Operational monitoring lets validator operators detect issues early and respond before incidents escalate. FoxxOne Validator Alerts (@FoxxWatch_bot) provides Telegram notifications for missed blocks, jailed validator events, governance proposals, and stake movement monitoring.

This enables faster response when validator health changes.
