Network Performance Summary – 13th August 2026
This summary presents the findings from 30 network performance (speed) tests conducted on 13th August 2026. Both average and median results are presented to provide a more reliable assessment, as averages can be influenced by outliers caused by devices, environmental conditions, speed-test interruptions, or random events along the Internet path to M-Labs.
Key Findings
Airtel: Airtel recorded an average video quality of 1152p, an 18% improvement from the previous period. Average download speed increased significantly by 990% to 99.2 Mbps, while upload speed remained stable at 12 Mbps and latency at 64 ms. However, the median download speed was considerably lower at 19.8 Mbps, indicating that a few very high results may have increased the average. Median upload speed was 8.9 Mbps, with median latency at 73 ms.
MTN: Video quality improved by 36% to 978p, while upload speed increased by 19% to 18.1 Mbps. However, average download speed fell sharply by 93% to 8.1 Mbps. Latency remained relatively stable at 54 ms. The median download speed of 2.9 Mbps confirms that low download speeds were common across the tests. Median video quality was 720p, upload speed 11.5 Mbps, and latency 57 ms.
Zamtel: Zamtel delivered the strongest and most consistent results. Video quality improved by 21% to 1200p, while average download speed increased by 94% to 198.5 Mbps. Upload speed remained stable at 13.5 Mbps, while latency improved by 30% to 69 ms. The median results matched the averages across all indicators, confirming that the strong performance was consistent rather than driven by outliers.
Overall performance was mixed across the three operators. Zamtel recorded the strongest and most consistent performance, with the highest download speed and matching average and median results. Airtel showed substantial improvement in average download speed and video quality, but its lower median download speed points to variability in performance. MTN improved in video quality and upload speed but experienced a significant decline in download performance, making download speed the main area requiring attention.
Website Availability
A total of 5,730 tests were conducted across 57 monitored websites in which 4,778 tests were uncensored, 331 tests recorded anomalies, 621 tests failed while zero tests confirmed website blocking.
Website availability was generally good, with the majority of tests completed successfully and without censorship. The failed and anomalous tests may have resulted from temporary network conditions, server availability, or other technical factors. No website was confirmed as blocked or censored.
Instant Messaging Applications
Facebook Messenger
Out of 230 test runs: 204 tests were uncensored, 26 were anomalous with zero confirmed blocked.
Telegram
Out of 231 test runs: 212 tests were uncensored, 19 were anomalous with zero confirmed blocked.
WhatsApp
Out of 232 test runs: 212 tests were uncensored, 20 were anomalous with zero confirmed blocked.
Signal
Out of 232 test runs: 208 tests were uncensored, 24 were anomalous with zero confirmed blocked.
All four applications—Facebook Messenger, Telegram, WhatsApp and Signal remained accessible, with most tests recording successful and uncensored access. While some anomalies were observed, there was no confirmed blocking or deliberate interference with any of the monitored platforms.
In conclusion the 13th August 2026 monitoring results indicate that Zamtel provided the strongest and most consistent network performance, while Airtel demonstrated significant improvement but with considerable variation in download speeds. MTN recorded improvements in video quality and upload speed but experienced a substantial decline in download performance.
Importantly, no monitored websites or instant messaging applications were confirmed to be blocked or censored. Continued monitoring will be important to determine whether the observed anomalies, failed tests and variations in network performance are temporary conditions or part of longer-term trends.
