# TelcoAIO

> TelcoAIO provides free browser tools for network and telecom engineers: IP/subnet planning, DNS, ASN/BGP, RPKI/IRR, configuration review, AI network fabric sizing, and evidence-linked submarine cable incident tracking. A separate native iPhone app provides on-device network diagnostics. No website signup is required.

Local calculators run in the browser. Live lookups depend on public services and their observation points; the cable tracker uses a server-side collection service. A successful lookup is not proof of complete, current network visibility.

Cable incidents distinguish published-report evidence from suspected network anomalies. Traffic drops, BGP changes, and probe failures alone do not confirm a physical cable fault or identify a specific cable. Network recovery is not proof of physical repair. Check source links, event dates, and collection freshness; missing or stale data does not establish that a cable is healthy.

Canonical tool URLs use `https://www.telcoaio.com/<tool>` without `.html`. English has no suffix; localized pages use `_cn` (Simplified Chinese), `_tw` (Traditional Chinese), `_ja`, `_ko`, `_de`, `_es`, and `_pt` (Brazilian Portuguese). Use the page's `hreflang` links to find available translations. The JSON index contains only locales with tool specifications, not every translated page.
