On 2026-04-07, Russia’s internet regulator Roskomnadzor said a widespread Runet outage was caused by a fault in Rostelecom’s network, not by the powerful DDoS attack the company reported a day earlier. The split between the cyberattack report and the regulator’s explanation matters for how Russia secures and manages its core internet infrastructure. The key question is whether the disruption was mainly a technical failure, a cyber incident, or a mix of both, which would shape future safeguards and accountability.
Reported Facts
Observable data points shared across all narratives
- •On 2026-04-06, Rostelecom reported that its network had come under a powerful DDoS attack.
- •Rostelecom said the DDoS attack had been repelled and that services were being restored.
- •Around the same time as the reported attack, users across Russia experienced a large-scale Runet outage.
- •Roskomnadzor later stated that the Runet disruption was linked to a fault in Rostelecom’s network infrastructure.
- •The regulator’s statement on 2026-04-07 did not attribute the outage to the DDoS attack.
- •Rostelecom operates a large share of Russia’s backbone internet infrastructure, including traffic for other providers.
- •Russian media reported that the outage affected access to multiple websites and online services inside the country.
- •No Russian official publicly named the source or origin country of the reported DDoS attack.
Core Disagreement— Main Cause
According to Russia, outage linked to both ddos attack and internal network fault. However, Regional sources see it as outage mainly caused by rostelecom’s own network fault.
Narrative Split
How different information blocks interpret these facts
REGIONAL
Infrastructure Weakness Concerns
Regional and independent outlets stress that Roskomnadzor blamed the Runet outage on a Rostelecom network fault, not on the DDoS attack the company highlighted. This framing points to structural weaknesses and mismanagement inside Russia’s core internet infrastructure rather than only outside cyber threats. These outlets expect further outages unless there is more transparency about causes and investment in modernizing the network.
- •Roskomnadzor publicly attributed the Runet disruption to a technical fault in Rostelecom’s network.
- •Rostelecom’s explanation centered on a powerful DDoS attack rather than internal failures.
- •The scale of the outage suggests that Russia’s internet relies heavily on Rostelecom’s backbone.
- •Concentrating so much traffic through one operator increases the risk of nationwide disruptions.
- •Lack of detailed public reporting on the fault makes it hard to assess how serious the weaknesses are.
RU
Cyberattack And Fault
Russian outlets describe Rostelecom as having faced a powerful DDoS attack while also dealing with an internal network fault that disrupted Runet. This view spreads responsibility between hostile actors targeting Russian infrastructure and technical weaknesses inside Rostelecom’s systems. Russian coverage expects regulators and the company to tighten defenses and improve reliability without dwelling on blame for the outage.
- •Rostelecom’s backbone network came under a powerful DDoS attack on 2026-04-06.
- •The company’s technical teams repelled the DDoS attack and restored network operations.

Outage linked to both DDoS attack and internal network faultRegional
Outage mainly caused by Rostelecom’s own network faultSo what
Readers cannot tell whether to treat this mainly as a cyberattack story or as a case of poor infrastructure management.

Hostile actors and technical issues share responsibility for disruptionRegional
Rostelecom’s dominance and mismanagement are central to the problemSo what
The split view changes whether the answer is more security spending or structural reform of Russia’s internet market.
Technical Details○Nobody Covers
No block provides a clear technical description of the specific fault inside Rostelecom’s network or how it interacted with the DDoS attack, making it impossible to judge how preventable the outage was or how likely it is to happen again.
Official Probe▸What to Watch
If Roskomnadzor or another Russian body publishes a detailed incident report or audit in the coming weeks, it would clarify whether the outage was primarily due to cyberattacks, internal errors, or structural weaknesses in Rostelecom’s infrastructure.
What Could Happen If...
- ▸If Roskomnadzor conducts and publishes a detailed investigation into the outage and DDoS attack Russian authorities may order Rostelecom to upgrade backbone equipment and diversify routing, which could reduce the risk of future nationwide disruptions.
