Network data from NetBlocks confirm a significant slowing of internet service for many users in Zimbabwe on Sunday 20 February 2022, as a major political opposition rally is held in Harare. The incident impacts multiple operators and has prevented live streaming from the Yellow Sunday demonstration, which seeks to unseat the ZANU–PF ruling party.
The root cause of Sunday’s network disruption has not yet been conclusively identified, but metrics are potentially consistent with the slowing, or throttling, of service.
Zimbabwe authorities have previously shut down internet access ahead of planned protests and during fuel price demonstrations.
