Reports of a submarine cable break near Taiwan are affecting connectivity into the Matsu Islands and some wider Pacific transit paths. This is the kind of outage that often never flips a Starlink or Peplink status page to red — but crews and island sites still feel it on latency and packet loss.
What we are watching
- Latency and jitter spikes on Pacific routes that transit Taiwan-adjacent cable systems.
- Island and coastal sites that depend on submarine backhaul rather than satellite primary.
- Whether a vessel’s Starlink path is fine while a shore office on fibre is not — two different problems.
GMTS lists this on our Network status page under Regional — Pacific because public cable damage is rarely mirrored on vendor status dashboards.
