01 / Definition

What it means.

A platform block targets a specific service—social media, messaging app, or website—while leaving the broader internet accessible. Platform blocks are typically implemented through a combination of DNS blocking, IP blocking, and SNI filtering.

Platform blocks are often announced officially (regulatory action) or occur without acknowledgment. They may be permanent, temporary, or triggered by specific events.

02 / How We Detect This

What we look for.

We test connectivity to platform-specific endpoints including web, API, and app servers. When multiple test types (DNS, HTTP, TLS) fail for a platform while general internet access remains functional, we identify a platform block. We confirm by testing from multiple probes within the affected network.
