The NetBlocks internet observatory has identified critical infrastructure outages across Venezuela starting 8:55 PM UTC (4:55 PM VET) Thursday 7 March, as a power disruption has knocked much of Venezuela’s internet connectivity and its utilities offline. The outage is the largest in recent network measurement records across Latin America.

The disruptions come at a critical moment for political discourse and democracy in the country, which has been in the midst of a power transition since early January. Impacted regions from NetBlocks’ real-time data include Caracas (Distrito Capital), Aragua, Bolivar, Carabobo, Cojedes, Guárico, Vargas, Táchira, Mérida, Zulia, Maracaibo, Barinas and Nueva Esparta. Earlier today, YouTube was censored for over 20 hours and fears have been raised over the possibility of a larger blackout.

Internet-scale network measurements indicate which regions have been affected and to what extent. During previous network and power outages, concerns were raised about attacks and military activity, and the risk of human rights violations perpetrated under the cover of darkness.

The current outages are the largest measured in 2019 in magnitude and extent, spanning across Caracas and having an impact across several major population centers. In previous incidents, hospitals reported failures of intensive care units although the rising human impact to local communities remains unknown.

NetBlocks diffscans, which map the entire IP address space of a country in real time, show internet outages corresponding to power cuts in the region.

Internet outages caused by electricity grid disruptions have a distinct network pattern used by NetBlocks to determine and attribute the root cause of an outage, a process known as attribution which follows detection and classification stages.

The timing and coincidence with events of political significance in the region are likely to fuel suspicions and mistrust during the crisis. It is to be noted that the country does experience frequent power cuts, and Venezuela started power rationing and reduced its electricity consumption to about 14,000 megawatts at peak hours because of the economic crisis in 2018, making it difficult to produce a conclusive determination. NetBlocks historic data suggest that incidents of this scale are rare.

Update, Friday 8 March 2019

Venezuela has been without power for 17 hours. New connectivity charts show some of the last remaining networks falling offline with generators and backups depleting and cell towers shutting down:

Methodology

NetBlocks diffscans, which map the IP address space of a country in real time, show internet connectivity levels and corresponding outages. Purposeful internet outages generally have a distinct network pattern used by NetBlocks to determine and attribute the root cause of an outage, a process known as attribution which follows detection and classification stages.
