Oracle Downtime

1 min read
Pronunciation
[awr-uh-kl down-tyme]
Analogy
Like a weather station going offline and failing to report temperatures, leaving forecasts outdated.
Definition
Periods when oracle nodes fail to submit attestations or updates, potentially causing stale data on‑chain and disrupting dependent smart contract operations.
Key Points Intro
Oracle downtime metrics track data availability and freshness for reliability guarantees.
Key Points

Heartbeat: Regular liveness attestations from nodes.

SLA impact: Downtime breaches service-level agreements.

Fallback: Backup nodes or cached data usage.

Alerting: Notifies operators on missed updates.

Example
An oracle monitoring tool alerts when a node misses three consecutive price report intervals, indicating downtime.
Technical Deep Dive
Monitoring job queries `latestRound` on oracle contract. If `block.timestamp – latestTimestamp > threshold`, triggers alert via Alertmanager.
Security Warning
Extended downtime can freeze DeFi protocols relying on price feeds; implement emergency fallback prices.
Caveat
Fallback data may be less accurate; use conservative values.
