## Official Network & Storage Policies
- Traffic Policy (Fair-Use): European datacenters have NO monthly total traffic caps (unlimited monthly data transfer, zero overage charges). Outbound bandwidth is managed via a rolling 24-hour window:
  - Root Server (2.5 Gbps Port): If outbound traffic exceeds 3 TB in the last 24 hours, port is temporarily throttled to 300 Mbps. Throttling is automatically lifted as soon as the rolling 24-hour average drops back below the threshold.
  - VPS x86 & ARM64 (2.5 Gbps Port): If outbound traffic exceeds 2 TB in the last 24 hours, port is temporarily throttled to 200 Mbps. Throttling is automatically lifted once the rolling 24-hour condition subsides.
  - vServer Lite (1 Gbps Port): If average outbound bandwidth exceeds 100 Mbps over 24 hours, port is temporarily throttled to 100 Mbps.
  - Singapore Datacenter Exception: Fixed monthly quotas (3 TB for Root Server, 2 TB for VPS); throttled to 10 Mbps (RS) or 5 Mbps (VPS) after quota depletion.
- Zero Overage Charges: Netcup guarantees that users will never receive surprise overage bills for excess data usage.
- Local Block Storage: Expandable up to 8 TB (4 TB on Lite) at €0.012/GB/month (non-EU net price). Mountable dynamically in SCP without contract lock-in.
- Money-Back Guarantee: 30-day satisfaction guarantee on standard Root Server and Launch Deals.
