Per-ISP signals are measured when the country shows anomalies (and continuously for pilot countries); «No data» means no anomaly drill has been needed recently.
ℹ️ How to read this page
Operational — signal at normal levels for this country / provider
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.
