How we decide the colours

checkinter.net is measurement-based and independent. We never rely on ISPs to tell us they're down — we infer it from public network data.

The three layers

Your side — measured live in your browser: how quickly a tiny file loads from a global edge, an international host and a Namibian host. If the page loaded but nothing else does, the problem is your device, Wi-Fi or LAN.
Your ISP — per-network signals keyed on each operator's ASN.
Upstream / backbone — country-wide signal, international latency, and submarine-cable health (WACS, Equiano).

Cloudflare Radar — per-country and per-ASN traffic vs. normal, plus outage annotations. (CC BY-NC 4.0)
IODA (Georgia Tech) — near-real-time outage scores from BGP routing, active probing and traffic telescopes.
Globalping — live latency and packet loss measured from probes, including inside Namibia.
Curated incidents — for cable maintenance and events that have no clean API, we add a short, dated note and label it "Curated".

Operational — signals are within normal range.

Degraded — a meaningful dip (e.g. traffic well below the usual band for the time of day, elevated latency or loss) that hasn't fully cut off.

Outage — strong, corroborated evidence of a hard drop (e.g. an IODA outage plus a large Radar traffic collapse).

No data — not enough signal to judge (e.g. a network we don't yet monitor).

To avoid flip-flopping on noisy data, a status must persist for a short window before we change the colour.

This is best-effort information, not a service-level guarantee.
We can see that something is wrong more easily than exactly why; the layer breakdown is a strong hint, not a verdict.
We're not affiliated with any ISP or regulator.
