French outlet Blast reported that the prime minister prepared a cutoff of major social networks for October 24, and that internet providers were asked to get ready for temporary DNS blocks on the platforms involved. It is an unconfirmed exclusive, and Blast's account concerns preparation, not a block that took effect.
DNS, the Domain Name System, is the internet's phone book: it turns a name like a social network's address into the numeric address a device connects to. A DNS block tells an ISP's servers to stop answering that lookup, so the site appears to vanish for that provider's customers.
It is also the lightest tool a government can pick. Anyone who switches to a third-party DNS resolver or uses a VPN can usually get around it in minutes. The platforms' servers stay online, and so does any app that connects by numeric address. A DNS block signals intent more than it guarantees a blackout, and it is cheap to set up and cheap to lift. That fits the word "temporary" in the claim.
The approach also differs from the cruder shutdowns seen elsewhere. Turkey has throttled social platforms during crises, and Russia has blocked them outright. Those methods work deeper in the network and are harder to dodge. A DNS-level plan would look closer to a trial run than a full cutoff.
The open questions are what prompted the plan for October 24, which platforms were on the list, and what legal authority the government would have invoked. Blast's reporting, as presented, does not settle any of them.
