Contabo's 10TB/100Mbps VPS—marketing trick or oversight?

I have signed up for a VPS at Contabo with the following specifications: 10TB monthly transfer, but the port is limited to 100Mbps. As far as I know, this is advertised as "unmetered" on their landing page, yet the TOS explicitly states the 10TB cap. I did the mathematics and to be precise, a sustained 100Mbps transfer over 30 days equals approximately 32.4TB. Therefore, the port limit makes the 10TB cap unreachable in practice, unless my calculation is incorrect. I am wondering whether this is a deliberate marketing strategy or simply an oversight. To be precise, has anyone else observed similar contradictions in Contabo's offerings? I am particularly interested from a GDPR documentation standpoint, as misleading specifications could constitute a violation of consumer transparency requirements.

Hej, Fritz48, you count good. But on server, 100Mbps is not for download only, is upload too. So if you do both, maybe you get more? No, I think they not want you to use 32TB. I have malý server on OVHcloud, they write "unmetered" but into config I see limit 5TB. Same thing. They hope you not notice.

This is a classic capacity planning mismatch, not a transparency issue yet. From an SRE perspective, I'd want to see their error budget for this product line—if 0% of customers can hit the stated limit, the limit exists only for abuse deterrence. I've seen this at my own shop: we had a "200Mbps unmetered" plan where the 200Mbps was the actual guardrail. We published a blameless postmortem when a customer proved the math and we had to clarify. Contabo needs similar transparency here.

Full-duplex Ethernet at 100Mbps provides 100Mbps in each direction simultaneously. The 32.4TB figure is for simplex; duplex would yield roughly 64.8TB theoretical maximum. However, this is irrelevant to the contradiction Fritz48 identified.

The term "unmetered" in hosting has a specific meaning: no metering, no billing for overage. A 10TB cap with overage fees or suspension is metered by definition. Contabo is using the term incorrectly, or their product team and legal team are not aligned. I would check whether their IRR entries match their BGP communities for traffic engineering—some providers shape aggressively at the edge rather than billing.

The Page said "unmetered" and now The Page says "10TB Fair Use" and I am thinking they changed it. I took The Screenshot at 14:30 today and now at 16:00 The Page is different. The Vord "unmetered" is gone. This is not The Good Look for The Contabo. I am thinking someone is wery fast with The Editing.

@debDebi This silent modification raises serious concerns under Article 5(1)(a) GDPR—lawfulness, fairness and transparency in processing. If Contabo processes personal data (billing, traffic logs) based on terms they alter without notification, the legal basis may shift without data subject awareness. I am reminded of Article 13 flashbacks from the copyright directive debates: platform obligations to inform users of changes. A provider must maintain versioned terms. I would request their records of processing activities under Article 30 to verify when this change occurred.
