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 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.
