Network metrics corroborate user reports of difficulty getting online amid widespread protests and the reported use of live fire by security forces.
Fixed-line and cellular services are understood to be affected for the second time in recent days. The disruption has had partial impact but is likely to significantly limit the free flow of information from the scene of the protests. Work is ongoing to monitor the situation.
Earlier this week the United Nations human rights office expressed deep alarm at the situation, alleging heavy-handed policing in response to anti-government protests over the weekend.
Some voices in Colombia’s media have called for the deployment of internet censorship to quell the unrest, although many more have spoken to the need for internet freedom and access to communication as a human right amid the crisis.
Operator Movistar subsequently issued a statement asserting that service had been disrupted by unidentified parties in an act of vandalism. The Ministry of Information Technologies and Communications reassured connectivity as a right for all Colombians, placing the number of subscribers at 7000 and stating that some maintenance efforts had been delayed due to public disorder.
