Tanzania experienced a brief but measurable degradation in internet connectivity on the evening of June 27. The disruption was observed between 19:10 and 19:40 UTC, lasting approximately 30 minutes. The primary technical indicator affected was a drop in active network reachability across the country’s IPv4 address space.
Technical Details
The event recorded a severity score of 627. The ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes, showed a 22% drop from its peak value during the observation window. Other signals showed varied behavior; the BGP control plane, which reflects routing advertisement visibility, remained stable with no significant drop observed. The merit-nt signal, a proxy for aggregate connectivity, registered a more pronounced drop of 69% from its peak.
