Practical monitoring guides.
Monitoring strategies, alerting approaches and operational setup guidance for the infrastructure, domains and dependencies your product relies on. For the incident stories behind them, read the blog.
Understanding DNS, SSL, email authentication and registrar risk: the quiet failures that rarely show up as downtime until they do.
How SSL certificate expiry causes unexpected downtime
A certificate is valid until the second it is not. Why expiry is the most predictable outage in infrastructure, and one of the most common.
How email authentication quietly breaks deliverability
SPF, DKIM and DMARC decide whether your mail is trusted. When they drift, delivery declines with no error to point at.
The most preventable outage: a lapsed domain registration
A missed renewal can take down everything at once. Why it still happens, and how to make it impossible to miss.
Which DNS records to monitor, and what should trigger an alert
A practical setup: the records that matter, what should page you, and how to avoid alerting on your own changes.
Operational visibility across APIs, endpoints and the services your product actually runs on.
Website uptime vs real customer experience
A site can be up and still unusable. Why uptime is one input to operational health, not the whole picture.
What API latency metrics actually matter
Averages hide the problem. A practical guide to percentiles, segmentation and the thresholds worth alerting on.
Tracking the platforms your infrastructure depends on, and catching their incidents before they become yours.
When the edge fails: detecting Cloudflare incidents early
Edge degradation rarely stays at the edge. How a Cloudflare incident propagates, and where the first signal appears.
How to monitor third-party providers without alert fatigue
Watching every provider is easy. Doing it so one incident produces one useful alert, not forty, is the real work.
