API Outage & Failure
Detection Platform
Detect downtime, HTTP 5xx errors, socket timeouts, and silent schema breakages in seconds. Multi-region quorum consensus eliminates 3 AM false alarms.
The 5-Stage Automated Outage Lifecycle
From initial anomaly detection to multi-region voting, on-call alert routing, and automated recovery.
Probe Anomaly Detected
An edge runner in US-East receives an unexpected HTTP 502 Bad Gateway or socket timeout on a scheduled probe cycle.
Multi-Region Verification
Probe nodes in EU-Central and AP-South immediately execute concurrent verification requests to confirm whether the outage is global or a local ISP blip.
Automated Incident Open
Quorum confirms failure. Uptara opens an active incident, starts the MTTR downtime clock, and dispatches rich diagnostic alerts within 1.5s.
Triage & Root Cause
On-call engineers receive the exact HTTP status, failed assertion, response headers, latency spike chart, and a ready-to-run curl reproduction snippet.
Verification & Closure
When services recover, Uptara requires consecutive multi-region green passes before declaring RESOLVED, calculating final downtime duration.
API Outage & Failure Classifications Handled
Uptara inspects every protocol layer to identify exact failure root causes.
| Failure Category | Representative Errors | Detection Logic | Default Urgency |
|---|---|---|---|
| HTTP 5xx Server Errors | 500 Internal Server Error, 502 Bad Gateway, 503 Service Unavailable, 504 Gateway Timeout | Instant HTTP status code verification on response headers. | Critical / P1 |
| TCP & Socket Connection Drops | ECONNREFUSED, Connection Reset by Peer, Connection Timed Out | Socket establishment timeout thresholds (default 5000ms). | Critical / P1 |
| SSL / TLS Certificate Failures | SSL Handshake Failed, Certificate Expired, Untrusted Authority, Hostname Mismatch | TLS handshake certificate chain inspection with 30-day proactive expiry alerts. | High / P2 |
| Silent Logical & Schema Failures | HTTP 200 OK returned with {"error": "Database pool exhausted"} or missing keys | JSONPath payload assertions (e.g. $.status == "success"). | High / P2 |
| Latency SLA Degradation | p95 API response times spiking from 45ms to 3200ms during deployment rollouts | Configurable latency ceiling threshold alerts before hard timeout crashes. | Medium / P3 |
| DNS Resolution Failures | NXDOMAIN, SERVFAIL, DNS propagation delays during nameserver migrations | Edge DNS resolver lookups across global authoritative nameservers. | Critical / P1 |
How Anti-Flapping Thresholds Protect Your On-Call Engineers
During rolling Kubernetes deployments or pod restarts, an API endpoint may momentarily drop a single TCP packet. Traditional uptime tools instantly blast SMS and email alerts, creating alert fatigue. Uptara allows you to configure confirmation thresholds (e.g. require 2 failed probes across a 2-of-3 quorum). You get 100% confidence on real outages without 3 AM false alarm panics.
Frequently Asked Questions: API Outage Detection
Uptara combines two defensive layers: distributed 2-of-3 multi-region quorum consensus and configurable anti-flapping failure thresholds. When a single region encounters an anomaly, adjacent probe nodes in Europe and Asia immediately cross-validate the endpoint. If the failure is localized to a transit ISP hop, no alert storm is generated.
Alerts sent to Slack, WhatsApp, Discord, PagerDuty, or custom webhooks contain actionable root-cause context: the failing URL, HTTP status code (e.g. 502 Bad Gateway), response time, failing assertion, affected regions, a formatted curl command to reproduce the issue from your terminal, and a direct link to the live incident dashboard.
Uptara timestamps the exact millisecond quorum confirmed downtime and tracks the incident continuously until consecutive green passes across all monitored regions confirm recovery. Total duration is logged and rolled into hourly, daily, and monthly SLA and MTTR metrics.
Yes. You can route critical P1 outages (e.g. 5xx errors or socket drops on checkout APIs) to PagerDuty and WhatsApp, while routing latency degradation or staging alerts to dedicated Slack or Discord channels.
