In the evening of 12 January 2019, the NetBlocks internet observatory had collected technical evidence of the blocking of all editions of Wikipedia in Venezuela. The restrictions were being implemented by CANTV, the largest telecommunications provider in the country. NetBlocks identified a major network disruption affecting the telecommunications infrastructure, which coincided with other restrictions affecting Venezuelans’ ability to communicate and access information during the previous 24 hours. The cause is believed to be an attempt to suppress a Wikipedia article that listed newly appointed National Assembly president Juan Guaidó as "president number 51 of the Bolivarian Republic of Venezuela." The collected data also showed that a number of local websites had been recently restricted, indicating that recent political instability could be the underlying cause for what may be a tightening regime of internet control.
