Monitor Third‑Party Outages Using Two Signals
The article explains a two-signal approach to detect and triage third‑party provider outages: (1) the provider's official status feed and (2) synthetic checks that emulate user requests. The author, Kerolos, founder of OutageDeck, describes the strengths and blind spots of each signal, how to correlate them for more accurate incident triage, example curl commands for OutageDeck's keyless API and synthetic probes, and a practical alerting policy mapping signal combinations to on‑call actions. The post also recommends recording timestamps, regions, response codes, and incident identifiers to improve post‑incident reviews.
Practical operational guidance for monitoring third‑party dependencies; useful to engineering and ops teams but not industry‑shifting.

Key Takeaways & Evidence Grounding
- Author recommends using two separate signals to detect provider incidents: official provider status feeds and synthetic checks that represent user experience.
- OutageDeck normalizes official status sources across 172 providers and exposes a keyless read‑only API for provider status.
- Examples of useful synthetic probes include HTTP requests to critical endpoints, DNS lookups, small authenticated API transactions, read/write against non‑production objects, and multi‑region checks.
- The article provides curl examples for querying OutageDeck's API and for performing synthetic HTTP health checks with timeouts and status output.
- A practical alert policy maps combinations of provider status and probe results to different urgency levels for paging and notifications.

OutageDeck: Lessons from Tracking 96 Providers
The author built OutageDeck, a service that aggregates official status feeds from 96 cloud and SaaS providers. The project revealed there is no standard status format (most use Statuspage-style JSON but many are bespoke), provider timestamps can be stale so uptime must be measured by the poller's check time, and some official endpoints are unusable or overly granular. The backend is intentionally minimal — a Next.js app with Postgres and overlapping schedulers — costing about $55/month. OutageDeck exposes a public JSON API, embeddable badges, RSS per provider, and email alerts, while being open about data gaps and limitations of upstream feeds.
Monitoring What You Can't See
This technical guide explains production monitoring and alerting fundamentals: you cannot directly observe running systems, so you rely on proxies (metrics, logs, traces) to know whether services are healthy. It defines the four golden signals — latency, traffic, errors, and saturation — and explains why saturation uniquely predicts imminent failure. The piece distinguishes dashboards (visible monitoring) from alerting (automated paging on threshold breaches) and warns about alert fatigue from noisy alerts. It introduces SLOs and error budgets as numeric service commitments that drive operational decisions (e.g., 99.9% availability implies ~43 minutes allowed downtime per month). Practical advice covers tuning alerts, using correlation IDs and structured logs for debugging, and prioritizing user-impacting signals for on-call paging.
Audit Your Monitoring Stack Before the Next Incident
A practical how-to describing concrete checks to audit an application monitoring/observability stack and reduce the risk of outages caused by configuration drift. The piece lists specific failure modes to look for—stale PagerDuty escalation policies, monitors with no notification targets, dashboards with empty panels, endpoints deployed without monitors, superficial database checks, and error-tracking systems without alert thresholds. It emphasizes cross-tool audits (PagerDuty, Datadog, Grafana, Sentry, etc.) because blind spots appear in the gaps between tools, and recommends making audits repeatable or automated. The author notes they built a tool (Cova) that connects to monitoring tools, runs automated audits, and scans PRs to catch unmonitored endpoints before deployment.
