The Paper-Only Incident Train Signal Attic Ladder: Catching Quiet Clues Before They Become Outages
How “paper-only” incidents, layered observability, in-band telemetry, and inclusive practices create an early-warning ladder that lets teams catch small anomalies before they become full-blown outages.
The Paper-Only Incident Train Signal Attic Ladder: Climbing From Quiet Clues to Full-Blown Outages Before They Happen
In many postmortems, the story starts the same way: “We actually saw something weird a week ago… but it didn’t seem important at the time.” A low-priority ticket. A flaky test. A “warning-only” alert someone muted. A comment in a changelog about a hacky workaround.
These are paper-only incidents: problems that exist in the records, not yet in production headlines. They’re the quiet train signals in your system, flickering red long before the wreck.
This post explores how to build an “attic ladder” of observability that lets teams climb from those faint, analog-like clues to clear, actionable incident intelligence—before anything falls over.
We’ll look at:
- Why paper-only incidents are your earliest, cheapest warning
- How to design a layered “attic ladder” for observability
- The power of in-band, low-overhead telemetry as an early-warning fabric
- Building a holistic framework for different “disaster types”
- Connecting incident design to inclusion and accessibility
- Using signal amplification to turn tiny anomalies into visible priorities
- Keeping your early-warning ladder aligned with evolving systems
The Paper-Only Incident: Quiet Clues That Predict Loud Outages
A paper-only incident is any issue that only exists in:
- Tickets or JIRA boards
- Changelogs and PR comments
- Minor or low-severity alerts
- Informal Slack threads or email
- Non-blocking test failures or warnings
Nothing is “down” yet. Customers aren’t complaining. SLO dashboards are still green. But the system is whispering that something is off.
Patterns that tend to precede major incidents include:
- Repeated “flaky” tests around a specific component
- Tickets about “weird but recoverable” errors that nobody has time to chase
- Changelogs with phrases like “temporary workaround” or “quick fix”
- Alerts that auto-resolve but recur frequently
- Support tickets that don’t meet escalation thresholds but share a common root
When viewed individually, they’re easy to ignore. When aggregated, they tell a story: there is a slow-moving train heading toward the station.
Treating these paper-only incidents as first-class signals is the start of your attic ladder.
Building the “Attic Ladder” of Observability
Think of your observability as a ladder into the attic:
- At the bottom: raw, noisy, analog-like data (logs, traces, weak alerts)
- In the middle: patterns, correlations, and risk signals
- At the top: clear, actionable incident intelligence
You don’t jump from raw logs straight to perfect insight. You climb.
A practical attic ladder has these layers:
1. Raw Signals (The Floor)
This is everything that exists by default:
- Application logs, infrastructure logs
- Metrics counters and basic health checks
- Changelogs, PR comments, commit messages
- Support tickets and chat messages
Ask: What do we already have that we’re not listening to?
2. Weak Signals (First Rung)
Here, you formalize the fuzzy:
- Convert repeated log patterns into low-severity alerts
- Tag support tickets with structured labels (performance, data, auth, etc.)
- Mark “temporary workarounds” in code or changelogs
- Track flaky tests and warnings as explicit issues, not noise
The key is to record and categorize instead of silently tolerating.
3. Pattern Detection (Middle Rungs)
Now you look across time and systems:
- Are the same components showing up in multiple weak signals?
- Are certain services driving more low-priority tickets over time?
- Are “warning-only” alerts clustering around specific environments or releases?
Lightweight automation helps here:
- Dashboards showing trend lines of weak signals
- Queries or jobs that summarize recurring tags or components
- Weekly review of “near misses” and recurring paper-only incidents
4. Risk Translation (Upper Rungs)
At this layer, you turn patterns into explicit risk statements:
- “We have a rising number of recoverable timeouts on the checkout service.”
- “Three recent workarounds cluster around the same caching layer.”
- “Data quality warnings in ETL job X doubled this month.”
You can then:
- Create proactive “risk tickets” with clear owners
- Adjust alert thresholds pre-emptively
- Schedule capacity increases, refactors, or focused investigations
5. Actionable Intelligence (The Attic)
Finally, you surface this risk in the same place and format as real incidents:
- “Pre-incident” dashboards with risk indicators
- Runbooks that explicitly cover known weak spots
- Prioritized backlog items framed as incident prevention, not “tech debt”
The goal: climb from quiet clues to clear action before customers feel pain.
In-Band, Low-Overhead Telemetry: Early Warnings Without Heavy Tooling
Many organizations avoid richer observability because it feels like “more tooling, more agents, more dashboards.” That’s unsustainable.
Instead, aim for in-band, low-overhead telemetry—signals that ride on existing infrastructure and traffic, analogous to in-band backscatter models like Satori’s:
- Add lightweight headers or metadata to existing requests to track latency, retries, or feature flags
- Piggyback trace IDs and context on your current logging pipeline
- Use existing message buses (Kafka, SQS, etc.) to carry health events
- Extend current dashboards, rather than introducing new silos
Benefits:
- Minimal extra operational burden
- Easier adoption (no one has to learn yet another tool)
- Better coverage because you reuse the real traffic path
The aim is to create an unobtrusive fabric of early signals that can be amplified as needed.
A Holistic Early Warning Framework for All “Disaster Types”
Outages are not just “the site is down.” You need early warnings across different disaster types:
- Performance: slow APIs, increased tail latency, degraded UX
- Security: suspicious login patterns, permission anomalies, strange egress
- Capacity: rising CPU/memory, storage nearing limits, quota warnings
- Data quality: schema drift, missing fields, inconsistent aggregates
For each type, define:
- Early weak signals (paper-only incident stage)
- Pattern metrics (how these accumulate over time)
- Risk thresholds that trigger preventive action
Then map to stakeholders:
- SREs and ops
- Developers
- Security and compliance
- Data and analytics teams
- Product, support, and customer success
A holistic framework acknowledges that a tiny signal in one domain (e.g., data quality warnings) can be existential for another (e.g., finance reporting).
Inclusive Incident Design: Runbooks, Dashboards, and Alerts for Everyone
Early warnings are only valuable if people can understand and act on them. This is where inclusion comes in.
Design incident artifacts so they’re usable by:
- Senior and junior engineers
- On-call rotations across time zones
- Support and customer-facing teams
- People with varying levels of domain knowledge
- People with accessibility needs (visual, cognitive, language)
Practical steps:
- Write runbooks in plain language with clear “if X, then Y” steps
- Use consistent terminology between alerts, dashboards, and documentation
- Ensure dashboards are color-accessible and not reliant on red/green alone
- Include context in alerts: what it means, who is affected, what to try first
- Offer multiple views: a high-level business impact view and a deep technical view
Inclusive design turns the attic ladder into something anyone can climb safely, not a trapdoor that only experts know how to use.
Signal Amplification: Turning Tiny Anomalies Into Visible Priorities
Your systems constantly emit tiny anomalies. Most will never matter. A few will become the next big incident. You need a way to amplify the right ones.
Think like an operational amplifier (op-amp):
- Small input signals (an uptick in timeouts, a cluster of data warnings)
- Carefully designed gain (rules and heuristics for importance)
- A clean, prioritized output (a clear, visible risk signal)
Examples of operational amplification:
- An alert that only fires when three low-severity warnings occur in the same service within an hour
- A “risk score” that rises as related paper-only incidents accumulate
- Weekly “near miss” reviews where multiple weak signals are reclassified as a single, tracked risk
The objective isn’t to drown teams in noise. It’s to turn correlation into clarity and promote subtle patterns into visible, prioritized attention.
Keeping the Ladder Relevant as Systems and Risks Evolve
Your systems are not static. Neither are your risks. New products, architectures, and regulations appear; old signals become irrelevant.
To keep your attic ladder useful:
- Review incident patterns quarterly: what weak signals did we miss?
- Retire obsolete alerts and dashboards; stale signals breed distrust
- Update runbooks and playbooks when architectures change
- Introduce early-warning patterns for new technologies (e.g., serverless cold start patterns, LLM misuse signals, multi-cloud failover issues)
- Involve multiple roles in retrospective reviews to capture diverse perspectives
Treat your early-warning system like a product: it has users, a roadmap, and a lifecycle.
Conclusion: From Whisper to Warning to Action
Most catastrophic outages didn’t come from nowhere. The system whispered first—in logs, tickets, warnings, and changelogs. Those paper-only incidents are your earliest and cheapest opportunity to act.
By building an attic ladder of observability—from raw signals to weak signals, patterns, risk translation, and actionable intelligence—you give your organization a structured way to climb from quiet clues to decisive action.
Layer in in-band, low-overhead telemetry, a holistic multi-disaster view, inclusive incident design, and signal amplification, and you get more than observability. You get foresight.
In a world where complexity grows faster than headcount, the teams that learn to hear the whispers—and systematically climb toward them—will be the ones who avoid the loudest, most expensive outages.
Now is the time to audit your own paper-only incidents and ask: What is our attic ladder, and how high can it take us before the next train is even on the tracks?
