“Russians have struggled to access their Yandex emails, open work files or book taxis.”

Historical context of data center attacks

World War II saw similar bombing of critical infrastructure, leading to 'area bombing' tactics.

“During the Blitz of World War II, Nazi Germany’s Luftwaffe bombed British arms factories, but it also bombed ports and critical national infrastructure.”

Data centers as critical infrastructure

Data centers power essential services, including transportation, banking, and communication.

“Most governments have satellite-based backup systems, but satellites can only transmit a small percentage of the traffic that any country needs.”

Consequences of data center strikes

Attacks cause prolonged internet outages, disrupting daily life and economic activities.

“Your credit and debit cards would not work (unless you live in Sweden, Finland, or Australia).”

Data center warfare becomes inevitable

Data center attacks are now a standard tactic in modern warfare, affecting all future conflicts.

“As Ukrainians know, data center warfare is not just about inconveniences for internet-addicted citizens: It’s about targeting and disrupting backbone of modern societies and economies.”
