Uptime & web performance

Your web services, monitored without false positives.

Kolosili checks the availability and performance of your sites, APIs and journeys from multiple checkpoints. An outage is only declared once confirmed by quorum — you're alerted only when it's real.

Reliable alerts
Multi-checkpoint quorum: a real outage is told apart from a mere measurement error. No more false alarms at 3 a.m.
Performance you can see
Web Vitals (LCP, CLS, TTFB), load time and a Full Page Check in a real browser — not just « the site responds ».
Seen from Africa
Real checkpoints where your users are. The latency measured is the one felt in Lagos or Lomé, not from a distant datacenter.
Incident diagnostics
Where it breaks and why: DNS/TCP/TLS phases, traceroute, network waterfall and screenshots attached to every incident.

Frequently asked questions

How do you avoid false alerts?
An outage must be confirmed by several checkpoints (spatial quorum). A single checkpoint's local error is never taken for an outage.
What can I monitor?
URL/HTTP, ping, DNS, TLS certificates, TCP ports, transactional journeys, multi-step APIs and Full Page Check (real browser + Web Vitals).
Where do you monitor from?
Real checkpoints in Paris (EU hub), Lagos and Lomé — Johannesburg, Abidjan and Yaoundé are coming. You choose which per monitor.
Where is my data hosted?
On sovereign EU infrastructure (France), with secrets encrypted at rest and strict isolation between companies.
