November, 2025 Incident Updates

Starting from 21:43 there were massive carpet bombing ddos attacks against our customers/our infrastructure which resulted in - even due to multiple large capacity upgrades during the last weeks and months - sporadic packetloss. Attacks reached around 5 Tbit/s in peak traffic distributed across our network PoPs in NL and DE (Frankfurt). We are aware of this situation and immediately started to work on countermeasures, which were applied after ~22:00.

We are further checking options to fully resolve this, but we also need to say that this are attack sizes which we have not seen before like this. These attacks are probably related to the Aisuru botnet which is currently targeting multiple companies and is reaching bandwidths not seen like this before.

We are actively monitoring the situation and thank you in advance for your understanding!
