China experienced a brief, isolated connectivity disruption on Tuesday, July 15, 2026. The event was recorded on the merit-nt network signal, with a severity score of 6,739. The disruption lasted approximately one hour and twenty-two minutes, beginning at 15:08 UTC and ending at 16:30 UTC.
Technical Details
The primary impact was observed on the merit-nt signal, which recorded an 88% drop from its peak measurement during the observation window. The merit-nt signal is a backscatter measurement that serves as a proxy for aggregate connectivity.
Other major network signals showed minimal deviation. The Border Gateway Protocol (BGP) control plane signal, which measures routing visibility for prefixes, showed a negligible change. The ping-slash24 signal, measuring ICMP reachability across IPv4 /24 prefixes, recorded only a 3% drop from its peak. The gtr-norm signal, which tracks deviation from an expected traffic baseline, recorded a 23% drop.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
