An HTTP check from our Zimbabwe node sends a full GET request — DNS resolution, TCP handshake, TLS negotiation, and first-byte response — and records the status code and response time. This simulates what a server or user in Harare experiences when accessing an external web service. Zimbabwe is a mobile-first market with relatively low average bandwidth, and HTTP response times here reflect both the RTT from southern Africa and any bandwidth constraints on the terrestrial transit links.

CDN coverage of Zimbabwe is limited. Most CDN providers serve Zimbabwe from their Johannesburg PoP. Cloudflare, Akamai, and AWS CloudFront all have Johannesburg presence. An HTTP check from Zimbabwe to a CDN-fronted service will typically route to Johannesburg first, adding ~30 ms compared to a direct South African check. Total HTTP response time for cached CDN content from Zimbabwe is typically 40–60 ms. Uncached origin requests from Zimbabwe to European or US origins will accumulate 180–250 ms total response time.

A failed HTTP check from Zimbabwe — timeout or connection refused — while all other regions succeed is unusual for a publicly available service, and is most likely caused by a firewall or WAF rule that blocks African IP ranges broadly or Zimbabwean IP space specifically. Some services apply blanket blocks to African ASNs for spam or abuse reasons. Comparing against our South African node will indicate whether the block applies to the broader southern African IP range or is Zimbabwe-specific.

Zimbabwe's internet infrastructure is concentrated in Harare, where the country's main carrier facilities, IX, and data center capacity are located. ZINX (Zimbabwe Internet Exchange) operates the primary domestic peering point, allowing Zimbabwean ISPs to exchange traffic locally rather than routing all domestic traffic via South African transit. ZINX is a small exchange by international standards — its member count and traffic volumes are modest compared to JINX in Johannesburg — but its operation is significant for reducing the cost and latency of domestic traffic routing.

International connectivity from Zimbabwe routes almost entirely through South Africa. Harare connects to the international cable infrastructure via terrestrial fiber south toward Johannesburg, where it accesses the SEACOM, EASSy, SAT-3/WASC, and other submarine cable systems landing at Durban and Cape Town. The Harare-to-Johannesburg path runs approximately 28–35 ms. From Johannesburg onward, Harare-to-Frankfurt runs approximately 165–190 ms, and Harare-to-London around 175–200 ms. There is no submarine cable landing directly in Zimbabwe — all international capacity transits via South Africa.

The Zimbabwean carrier market is served by TelOne (AS37214), the state-owned fixed-line operator, and Econet Wireless (AS30969), the dominant mobile and data carrier. Africom (AS37553) and ZARNet provide alternative fixed connectivity. Liquid Telecom (now Liquid Intelligent Technologies, AS30844) operates a significant portion of Zimbabwe's fiber backbone and connects to its broader Sub-Saharan African network. Most commercial internet access in Zimbabwe is mobile-first — Econet has a far larger subscriber base than any fixed-line provider.

Zimbabwe's internet penetration and infrastructure quality have improved over the past decade but remain constrained by economic factors. Average fixed-line speeds are lower than regional peers like South Africa or Zambia. Last-mile fiber deployment is limited outside central Harare. The combination of transit dependency on South Africa and limited domestic backbone investment means that Zimbabwean internet performance is sensitive to conditions on the Harare-Johannesburg terrestrial link and on the South African IX and cable infrastructure beyond it.

A probe node in Zimbabwe gives a view from one of Sub-Saharan Africa's less-connected markets. Results from Zimbabwe are useful for assessing whether services are reachable from southern African land-locked markets and what latency users on South-African-transit paths experience. Because all international traffic routes through Johannesburg, results from Zimbabwe and from South Africa will often look similar for well-peered destinations, with Zimbabwe adding roughly 30 ms on top of the South African RTT.
