Russian bloggers warn Russia’s hyper-centralized digital economy is vulnerable.

The short version

  • When Russia began attacking Ukrainian data centers and telecommunication infrastructure, it apparently failed to prepare for possible retaliation.
  • Now Russia’s digital services are facing widespread outages after Ukrainian drone strikes knocked out three of the largest data centers owned by Russian tech giant Yandex within several days.
  • Pro-Kremlin bloggers are warning that Russia’s centralized digital economy could collapse because the country is not prepared for the “data center war” it started, according to posts translated by the pseudonymous independent researcher ChrisO_wiki .

What happened

The Russian commentators also suggested that Ukraine’s decentralized digital services could prove more resilient than Russia’s system if the countries continue trading such blows. Russia initially launched a drone strike campaign targeting Ukrainian data centers and mobile phone networks in late September.

Why it matters

It was not immediately clear how much damage may have occurred to the supercomputers, which are based on Nvidia A100 GPU chips.
