NetBlocks publishes original reporting on internet governance and sustainable energy, providing tools to the public to observe possible Internet blocks and to estimate the economic consequences of network disruptions.
On 25 November 2017, NetBlocks and Digital Rights Foundation provided information about the nationwide censorship of Facebook, Twitter, YouTube and other social media services by the Pakistani government following the Tehreek-e-Labaik protests.
During the 2018–2019 Sudanese protests, NetBlocks stated that the Sudanese government maintains "an extensive Internet censorship regime" following the censorship of social media websites in the country. Following the 2019 Gabonese coup d'état attempt, NetBlocks monitored censorship in the country. The cost of the three-day Internet shutdown following the Zimbabwe fuel protests was also calculated cost Zimbabwe an estimated $17 million.
The block of Wikipedia in Venezuela and other censorship incidents during the Venezuelan presidential crisis were also monitored by NetBlocks, with several international media outlets covering the situation with NetBlocks' work.
Visiting NetBlocks' website used to trigger monitoring checks against websites to see if they were blocked for that visitor. However, these checks were done without the user's consent, A researcher, Collin Anderson, argued that this could potentially present a risk to users. NetBlocks said it removed the checks in 2020 because the data "just wasn't that good," Wired reported.
In July 2020, as the Somalian Parliament passed a motion of no confidence in Prime Minister Hassan Ali Khaire, NetBlocks claimed internet access was shut down. Doug Madory, director of Internet analysis at Oracle, said that a damaged submarine cable caused the interruption. NetBlocks rejected the theory, citing an analysis of weather conditions.
Anderson, set up a website criticizing NetBlocks at the domain "netblocks.fyi". In September 2020, NetBlocks filed a complaint against Anderson with the World Intellectual Property Organization. The mailing list OTF-Talk reacted negatively to the response, and afterwards subscribers demanded NetBlocks to "release its tools as open source software, make its methodologies open to audit, and publish its measurement data so it could be scrutinised". NetBlocks won the complaint in November 2020 and took over the domain. Anderson subsequently moved the site to netblocked.org.
