Internet access - ADSL / VDSL [SEWAN] Unexpected disturbances - 08.10.2024

Beginning: 08.10.2024 – 10.13 AM

Ending: 08.10.2024 – 10.40 AM

Impact: Internet services

 

Dear customer, dear partner,

 

We recently suffered from Internet access issue. The situation is back to normal since 10.40AM today. Investigation on going.

 

After deeper investigation, we suspect that the ongoing cyberattack toward Belgian institution may have caused side effects on Sewan infrastructure.

At this stage, we can confirm that all the major ISP in Belgium have been impacted.

 

Several newspapers have already reported important national impacts:

At the moment, our security team is still investigating the impacts and the actions to take.
