Is Heap Down? How to Tell and What to Do

Is Heap Down? How to Tell and What to Do

Heap automatically captures every user interaction — clicks, taps, form submissions, page views — without requiring manual event instrumentation. When Heap degrades, that autocapture pipeline breaks silently. No SDK errors show up in your application, no user-facing failures appear. The data just stops.

The fastest way to know: Statusfield monitors Heap continuously and alerts you within minutes. Without monitoring, you discover Heap is down when you notice gaps in your retroactive analysis — sometimes days later.

Common Signs of a Heap Outage

Symptom	What's likely happening
Event counts drop unexpectedly	Autocapture ingestion pipeline is degraded
Heap dashboards not loading	Query or serving infrastructure is unavailable
Sessions missing from session replay	Session recording pipeline is impacted
Funnels showing unexpected drop-offs	Event processing backlog or ingestion failure
Cohorts not updating in connected tools	Heap → downstream integration sync is failing
heap.track() calls returning errors	Heap's API endpoint is unreachable or rate-limiting
Segment or Salesforce sync out of date	Heap's data connector pipeline is degraded

How to Confirm It's Heap, Not You

Before changing your Heap configuration or rolling back a deployment, rule out issues on your side:

1. Check SDK network requests in browser DevTools

Open DevTools → Network → filter for heapanalytics.com. Healthy Heap payloads return HTTP 200. Repeated 500 errors, timeouts, or connection failures with no corresponding code changes on your end indicate a platform issue.

2. Distinguish autocapture from manual instrumentation

Heap captures events automatically via its snippet, but you may also call heap.track() directly. If your manual heap.track() calls are failing but the page itself loads, the ingestion endpoint is likely degraded. If autocaptured events are missing but manual calls succeed, the issue may be in Heap's event-classification pipeline.

3. Check your Heap snippet load

A 403 or 404 when loading the Heap snippet (e.heapanalytics.com/js/heap-*.js) indicates the CDN or snippet service is down, not the ingestion pipeline. Both are Heap infrastructure, but they fail independently.

4. Verify your environment ID

A 401 or 403 response from the API with a valid snippet URL indicates an environment mismatch or key rotation, not a platform outage. Confirm the environment ID in your Heap settings matches what's in your snippet.

The Problem With Vendor Status Pages

Heap's status page is maintained manually. During an incident, the page typically lags 15–30 minutes behind the actual degradation onset — because SRE teams validate impact before posting publicly.

With autocapture analytics, the danger is compounding: there's no error surface in your application to trigger an alert. The product runs perfectly. Your users have no idea. The data just disappears from your analytics retroactively — and because Heap's value is built on complete historical capture, gaps are not recoverable after the window closes.

Statusfield monitors Heap continuously and fires alerts the moment it detects a degradation — before your retroactive analysis window starts accumulating gaps.

What to Do During a Heap Outage

Immediate (first 5 minutes)

1. Identify whether ingestion or querying is affected — is new data failing to capture, or are existing dashboards just unavailable? These require different responses.
2. Note the exact degradation start time — Heap's retroactive model means you need to annotate your analysis with the gap window after recovery.
3. Check downstream integrations — Heap syncs data to Salesforce, Segment, HubSpot, and other tools. If the sync pipeline is down, those systems stop receiving behavioral updates.
4. Assess your experiment exposure — if you're running A/B tests tracked through Heap, a data gap may affect statistical significance calculations.

Communication (first 15 minutes)

• Alert your product and data teams that behavioral data may be unreliable for this window.
• If you're in a high-stakes analysis period (product launch, growth experiment), document the exact outage window for future annotation.
• Do not make product or experiment decisions based on Heap data until ingestion is confirmed recovered.

Recovery

• After Heap recovers, check whether the ingestion pipeline backfills events that were queued during the outage. Heap's SDK buffers some events client-side, but this is session-scoped — events from closed sessions during the outage are unrecoverable.
• Annotate affected dashboards and funnels with the outage window.
• Review any cohort syncs that run on a schedule — they may need to be re-triggered if a sync window was missed.

Heap Components and What Each Outage Looks Like

Heap is composed of multiple systems that can degrade independently:

Component	Impact when degraded
Autocapture ingestion	All user interactions stop recording silently
Manual event API (heap.track)	Explicit tracking calls fail
Session replay pipeline	User session recordings not captured
Data processing / event classification	Events ingested but not queryable in dashboards
Dashboard / query layer	Analysis unavailable but data intact
Data connectors (Salesforce, Segment)	Downstream systems stop receiving behavioral data
Cohort export	Cohort syncs to ad platforms and CRMs paused

An ingestion outage is the most dangerous: data is simply not captured and cannot be retroactively recovered. A query-layer outage is recoverable — the data is stored, dashboards are just temporarily unavailable.

Why DIY Monitoring Misses Heap Failures

A simple uptime check on the Heap snippet URL gives you false confidence:

• The snippet loading does not mean ingestion works — the JavaScript loads from CDN while ingestion calls go to a separate endpoint. These fail independently.
• Autocapture has no error surface — there are no user-visible errors when autocapture breaks; your health check would need to verify actual event delivery, not just HTTP reachability.
• Processing lags look like outages — Heap's pipeline introduces a natural delay between capture and queryability; a monitoring check that validates "event appeared in dashboard" will generate false positives.
• SDK retry masking — Heap's SDK retries failed ingestion calls silently; a brief disruption may not surface in your logs until the retry budget exhausts.

Effective Heap monitoring needs to verify the full ingestion-to-query pipeline, not just CDN reachability. That's what Statusfield does.

Monitor Heap Before Your Behavioral Data Disappears

Statusfield monitors Heap and 1,700+ other services continuously. When something degrades, you get alerted — not after you notice missing sessions in your retroactive analysis.

3 monitors, 10 alerts/month, no credit card required.

FAQ

Is Heap down right now?

Statusfield monitors Heap continuously and will alert you before your behavioral data disappears. If you're seeing unexpected drops in event counts or missing sessions, check Statusfield for real-time status.

Why aren't my Heap events showing up?

Check your browser DevTools for network errors on heapanalytics.com. Repeated 500 errors on ingestion calls indicate a Heap platform issue. If the API is returning 200 but events aren't appearing in dashboards, the processing pipeline is lagging — the data may appear once the backlog clears.

How long do Heap outages last?

Most incidents resolve within 1 to 4 hours. Query availability typically recovers before full ingestion backfill completes.

How do I get alerted when Heap goes down?

Statusfield monitors Heap continuously and fires alerts the moment it detects a degradation — before your data disappears silently. Every plan starts with a free trial — no credit card required.
