Caiway

Caiway is a telecommunications operator headquartered in the Netherlands that provides broadband internet, digital television, and fixed‑line telephony services. The company delivers these offerings primarily over its own hybrid fiber‑coaxial cable network, which combines fiber optic backbones with coaxial last‑mile connections. Its product portfolio targets residential households as well as small and medium‑sized enterprises seeking reliable connectivity and entertainment packages. Caiway markets its services under the Caiway brand, focusing on the Dutch market where it competes with other national and regional providers. By owning and managing the physical infrastructure, the company can control service quality and introduce upgrades such as higher speed tiers and advanced TV features.

In August 2020 Caiway was among several European ISPs that experienced a short‑lived but disruptive distributed denial‑of‑service attack aimed at their DNS infrastructure. The assault employed DNS amplification and LDAP reflection techniques, reaching a peak traffic volume of approximately 300 gigabits per second before being mitigated within a day. Dutch authorities confirmed that the attackers had accompanied the traffic surge with Bitcoin extortion demands, although no definitive attribution was established. The incident highlighted the importance of robust DNS protection and traffic scrubbing capabilities for operators that rely on exposed name‑resolution services. Caiway’s involvement in the event underscores its role as a network operator that must maintain resilient core services amid evolving cyber‑threat landscapes.
