The regional government said the outage, affecting both mobile and home internet, is needed to repair the underwater fiber-optic line. Under favorable conditions, the entire operation will take up to four days.
During the work, the peninsula will rely on a backup satellite channel. Voice calls, SMS and landline telephones will continue to function, while messaging apps, social networks and other online services will be unavailable, according to TV Rain.
The satellite link will provide connectivity for emergency services, hospitals, banks, ATMs, gas stations, multifunctional centers and major retail chains. In smaller shops without backup connections, customers may be asked to pay in cash, The Insider reported. Authorities advised residents to withdraw cash in advance, pay for essential services, download offline maps and save taxi phone numbers.
Rostelecom, Russia's state-controlled telecom operator, will move the cable's landing point onshore near Cape Levashova to a safer location. The Sea of Okhotsk has been eroding the coastline, threatening the line with damage. According to authorities, an accident could have left the peninsula without communication for several months.
The final stage of repairs was originally planned for September 2025 but was postponed due to storms, freezing temperatures and the end of the navigation season for small vessels. Most of the work on the marine section was completed earlier.
The Insider found that during the line's construction, Rostelecom had planned to lay an additional cable between Magadan and Kamchatka as a backup route. The project was abandoned due to high costs, with the company instead burying the main cable deeper to protect it from fishing trawlers. As a result, the only backup for Kamchatka during the current repair will be the significantly less powerful satellite channel.
