Concurrently, other internet health indicators showed deviations. The gtr-norm signal, a measure of traffic volume, recorded a -75% drop from its peak. The merit-nt signal, an aggregate connectivity proxy, showed a -54% drop. The gtr signal, representing raw traffic, fell -28% from its peak. The ping-slash24 signal, measuring ICMP reachability across IPv4 network blocks, showed a -3% drop.
