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.
Recorded outages in China
No country-level outages recorded for China since 21 Jun 2026.
Submarine cables feeding China
If a national outage coincides with a fault on one of these systems, the cable is a likely cause - check its live page:

Internet in China: questions and answers
Is the internet down in China right now?
No. At the last check (21 Oct 2026 03:07 UTC) the internet in China was working normally: the signal was at its usual level.
When was the last internet outage in China?
No country-level outages have been recorded for China since 21 Jun 2026, when the records begin.
Which internet providers are watched in China?
GeoCables watches the leading providers of China: No.31 (25.2%), China Mobile (23.1%), China Unicom China169 (14.7%), China Telecom (5.7%), China Unicom Beijing (4.4%). The share is the part of the country's internet users served by the provider.
Which submarine cables connect China?
China is connected by 24 submarine cables in the GeoCables database, among them APCN-2, Asia Africa Europe-1 (AAE-1), Asia Direct Cable (ADC), Asia Link Cable (ALC). A break on one of them can slow down or cut international traffic.
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.
