Executive Summary
Claim 55 classifies a candidate remediation's blast radius statically, per action type, before it is ever attempted. That static classification has a blind spot: an action that is genuinely low-impact when it happens once, in isolation, can be part of something much larger when it is happening everywhere at once. AEGIS closes that blind spot with a correlation detector that watches, in real time, how many distinct sites and what share of the overall fleet are matching the same fault signature within a common time window.
When both a minimum-site count and a minimum fleet-proportion threshold are crossed simultaneously, the system reclassifies the entire matching pattern - occurrences that would individually be assessed as contained or cell-scoped - into a single fleet-scoped blast-radius classification, and suppresses autonomous remediation across all of them in favor of an escalated response. This happens regardless of how confident any individual occurrence's fix would otherwise be under Claim 54.
Problem Statement
A blast-radius model that only looks at one action in isolation cannot see the pattern formed by many simultaneous occurrences of the same fault. A restart, a cache flush, or a config rollback that is genuinely safe to run autonomously on one node can, if triggered simultaneously and independently across a large share of a fleet by the same underlying systemic cause, produce exactly the kind of coordinated, cascading impact that a static per-action classification was never designed to catch.
Why Existing Solutions Are Insufficient
- Static per-action blast-radius policies: Classify an action type once and apply that classification uniformly, with no mechanism to notice that the same action is currently happening everywhere at once.
- Alert-storm suppression/deduplication (common in AIOps platforms): Groups and deduplicates alerts for human visibility, but typically does not itself gate whether underlying automated remediation actions are allowed to keep firing autonomously during the storm.
- Rate limiting on individual automated actions: Caps how fast a single action type can fire, but a rate limit calibrated for normal operation is not the same as a correlation-aware circuit breaker that recognizes a specific cross-site pattern as systemic.
- Manual "declare an incident" processes: Depend on a human noticing the cross-site pattern and manually pausing automation, introducing exactly the detection lag this mechanism is designed to remove.
Technical Architecture
Cross-Site Correlation Detection
The system continuously tracks, per fault signature, the set of distinct sites at which that signature has matched within a common, bounded time window, alongside what proportion of the total monitored fleet those sites represent.
Dual-Threshold Trigger
Reclassification triggers only when both a minimum number of distinct matching sites and a minimum proportion of the overall fleet are crossed within the same window. Either signal alone - many sites in a very large fleet, or a small number of sites that happen to be a large share of a small fleet - is evaluated jointly rather than in isolation, so the trigger reflects genuine breadth of impact rather than either raw count or raw proportion alone.
Reclassification and Suppression
Once triggered, every matching occurrence across the correlated pattern - regardless of its individually-computed blast-radius tier or confidence score under Claim 54 - is reclassified into a single fleet-scoped blast-radius classification, and autonomous execution is suppressed across the whole pattern in favor of an escalated response.
Correlation Detection & Suppression Logic
| Condition | Description | Effect |
|---|---|---|
| Site-count threshold | Minimum number of distinct sites matching the same fault signature in-window | Necessary but not sufficient alone |
| Fleet-proportion threshold | Matching sites represent at least a defined share of the total monitored fleet | Necessary but not sufficient alone |
| Both crossed simultaneously | Combined signal of genuine systemic breadth | Triggers reclassification and suppression |
This mechanism operates as a dynamic, decision-time refinement layered on top of Claim 55's static blast-radius baseline: the static tiers still apply to every individually-evaluated action, but this correlation detector can override the outcome for a specific pattern of simultaneous occurrences, upgrading them collectively to fleet scope even when none of them would individually classify that way.
