“Measurements indicate that WhatsApp frontend and backend servers have become unavailable from Thursday afternoon. The restrictions are likely to limit the free flow of information online presenting a challenge to election transparency as polls are held.”

The restrictions on WhatsApp identified by Netblocks are on Zambian operators Zamtel (state-controlled), Airtel Zambia, Liquid Telecom, and MTN.
