Frequently Asked Questions

Enterprise S3-compatible object storage with full S3v4 API support. Reliable infrastructure for backups, logs, video, and data lakes across 6 datacenters on AS215197.

Transparent pricing with no per-request fees. €7.50/TB/month STANDARD_IA, €60/TB/month STANDARD (NVMe). Enterprise commitments unlock rates as low as €5/TB and €40/TB respectively. Egress €5/TB, down to €2/TB at volume. Own infrastructure on AS215197. European data residency, GDPR-compliant.

No. Unlimited PUT, GET, DELETE, LIST operations at no extra cost. No fair use limits or throttling. Buy 100TB, get 100TB with full performance.

Our STANDARD (NVMe) delivers single-digit millisecond latency comparable to hyperscaler premium/express storage classes. Which typically cost $110–250/TB. Starting at just €40–60/TB. We include unlimited API calls (hyperscalers charge per request) and egress from €5/TB down to €2/TB at volume (hyperscalers charge ~€90/TB). Total cost is typically 50–70% lower for comparable performance workloads.

Yes. Full S3v4 API: PUT, GET, DELETE, LIST, multipart uploads, bucket policies, ACLs, versioning, lifecycle management. Full IAM API for self-service access key management. Works with AWS CLI, all SDKs, Terraform.

STANDARD (NVMe): 2–10ms typical latency, matching hyperscaler express storage tiers that cost $110–250/TB. Ideal for real-time analytics, log ingestion, and latency-sensitive applications.

STANDARD_IA: 100–200ms typical latency, comparable to hyperscaler general-purpose tiers. During low-load periods, latency can drop to 10–20ms. Optimized for backups, archival, and sequential access workloads.

Own datacenters on AS215197. European locations: Germany, Netherlands. Choose your region, enable geo-replication. GDPR-compliant.

Bank transfer (SEPA), credit card via Stripe, and Bitcoin. First month requires upfront payment. Subsequent months are post-paid with NET30 terms. You receive an invoice for actual usage, payable within 30 days.

Fair billing that works in your favor. We use an average-based billing model that keeps your costs predictable and fair.

How it works: Every hour, we record how much storage you're using. Each day, we note your peak usage for that day. At month's end, we calculate the average of your daily peaks.

Why this benefits you: You're not punished for temporary spikes. Need to upload 50TB for processing, then scale back down? You'll only pay for the average, not the peak.

Example: If your daily peaks are Mon: 2TB, Tue: 10TB (big upload), Wed: 3TB (scaled back), Thu: 2TB. Your bill is (2+10+3+2)÷4 = 4.25TB.

We provision capacity for your peaks, but we bill you on the average of your usage.

Yes. The Customer Portal provides a full web interface for managing your storage. No CLI required. Browse and manage objects, upload and download files, create and revoke access keys, configure custom domains with automatic Let's Encrypt SSL, set up CORS rules, enable static website hosting, and configure geofencing (IP-based access control with country-level allow/deny lists). All self-service.

No. Egress is metered per GB and billed in volume tiers: €5/TB up to 100 TB per month, €3/TB up to 1 PB, €2/TB above that. There is no ratio between egress and stored volume and no monthly cap, so serving more than you store is fine.

Yes. Public assets use the public-read policy, paid content uses presigned URLs. A custom domain with Let's Encrypt TLS, Cache-Control defaults, CORS rules and HTTP range requests are built in, so HLS playlists and segments play straight from the bucket. Setup guide: Serving video and images.

Delivery is best effort over our own backbone with multiple 100 Gbit/s links and sites right next to DE-CIX Frankfurt and AMS-IX. There is no bandwidth cap per bucket. Request-rate limits exist per user and bucket; for sustained high request rates open a ticket and we raise them.
