ℹ️ How to read this page
Degraded - signal dip ≥20% below its 24h baseline - partial outage or major disturbance
Major outage - dip ≥50% - large-scale loss of connectivity
“Signal dip” compares the current BGP-visibility and active-probing levels against the median of the previous 24 hours, corrected for global measurement artifacts (a worldwide simultaneous drop is ignored).
Data refreshes hourly. Per-ISP rows are measured in depth when the country shows an anomaly (pilot countries - continuously). The probable cause is a heuristic: an active fault on a submarine cable feeding the country ranks first, then routing signals, then power/access patterns.

How does GeoCables detect an internet outage?
The status comes from two independent signals: routing announcements (BGP) and active probing of networks inside the country. A drop of 20% or more below the usual level of the last 24 hours is shown as degraded, a drop of 50% or more as an outage. See internet outages in all countries.
