@Star12Mt@masto.nyc Almost same here, in the Russia, Saint-Petersburg - old buildings have old-style landlines (cable with twisted pairs from the nearest telephone exchange), but new buildings don't have it anymore. Most of the telephony are passed via Ethernet cable, so usual ISPs also provides a telephony service nowadays, like the mentioned Rostelecom.
BTW, the article is badly fact-checked. Mobile internet outages don't cause the shutdown of cellular telephony - it still works, only mobile Internet is completely off.
Why is the Rostelecom's chief recommends to have a landline phone for every Russian? I dunno. Possibly, this is because his company could sell contracts to connect such phones - so this is just a marketing. Possibly, he is disconnected from the usual people and reality, like a lot of officials here.
