Contabo currently says its servers have no default bandwidth limit, but fair-use rules still apply and exceptionally high or disruptive usage may be throttled. That is not a blanket guarantee that every VPS can carry a 24/7 YouTube stream without restriction. Check the selected plan’s port speed and applicable traffic terms, estimate the stream’s monthly data, then test the actual route to YouTube. Contabo’s current documentation does not establish a guaranteed 24/7 streaming allowance or uninterrupted YouTube throughput.
What Contabo’s bandwidth policy means
As checked in Contabo’s current Help Center in 2026, the company says there is no default bandwidth limit for its VPS, VDS, or dedicated servers; its fair-use policy applies, and it reserves discretion to throttle exceptionally high or disruptive use. “No default limit” therefore does not mean that all traffic is unrestricted in every circumstance.
Contabo’s product documentation presents plan-specific port speeds and traffic terms, with the VPS plan table showing rates from 200 Mbps to 1 Gbps. Those are advertised port rates, not a promise of that much end-to-end throughput to YouTube or a guarantee that a persistent stream will be exempt from fair-use review. Confirm the exact plan, region, order terms, and current traffic wording before relying on a VPS for a continuous workload.

Port speed, stream bitrate, and monthly traffic are different
Port speed is the network link rate
A port speed measured in Mbps describes the nominal rate of the server’s network connection. It is a ceiling or plan specification, not a measurement of the route between that server and YouTube. Network congestion, packet loss, routing, shared infrastructure, and other workloads can affect actual performance.

Bitrate is the stream’s moment-to-moment data rate
YouTube’s current live encoder guidance recommends H.264 video bitrates of 14 Mbps for 1080p at 30 frames per second, 17 Mbps for 1080p at 60 frames per second, and 50 Mbps for 4K at 60 frames per second. These are YouTube recommendations, not Contabo measurements. A simple comparison puts these example rates below the 200 Mbps to 1 Gbps port rates displayed in Contabo’s VPS table, but that comparison alone cannot prove stability or uninterrupted delivery.

Monthly traffic is the accumulated volume
A 24/7 stream can use a modest rate at any given moment and still transfer a large amount over a month. A useful decimal estimate is:

Data in GB ≈ bitrate in Mbps × seconds ÷ 8 ÷ 1,000.

| Example video bitrate | Approx. per hour | Approx. per day | Approx. for 30 days |
|---|---|---|---|
| 14 Mbps (1080p30) | 6.3 GB | 151 GB | 4.5 TB |
| 17 Mbps (1080p60) | 7.65 GB | 184 GB | 5.5 TB |
Actual transfer can differ because of protocol overhead, audio, reconnects, other server traffic, and how the stream is encoded or relayed. If the VPS only relays a stream encoded elsewhere, establish which traffic direction crosses the VPS and where viewer playback is served; do not assume all viewer delivery traffic is counted as VPS outgoing traffic.
Does a 24/7 YouTube stream fit a Contabo VPS?
The advertised port-rate comparison suggests that the example YouTube bitrates are below the rates displayed for Contabo VPS plans. It does not establish the route’s real-world stability, policy treatment, or an explicit approval for continuous YouTube streaming. The official pages reviewed do not publish a guaranteed Contabo-to-YouTube throughput or an uptime guarantee for this use.

Before choosing a plan, evaluate each of these separately:
- Plan rate and terms: Check the exact plan’s advertised port speed and any location-specific traffic allowance or fair-use wording.
- Required stream rate: Select the YouTube bitrate for the intended codec, resolution, and frame rate, including audio and a margin for overhead.
- Expected total: Estimate outgoing data for the actual hours streamed, then account for unrelated server traffic.
- Encoding load: If the VPS encodes the video, CPU capacity and encoder workload matter in addition to bandwidth. If it only relays an already-encoded stream, identify which network traffic passes through it.
- Route and stream health: Test the actual upload path to YouTube and monitor YouTube’s stream-health indicators during a preflight run. A speed test is useful evidence, not proof of 24/7 reliability.
YouTube recommends testing upload bitrate, making sure total stream bitrate fits available upload bandwidth, and monitoring stream health. Its guidance also provides codec-specific settings and keyframe recommendations; use the settings that match your encoder and planned resolution rather than treating the port rate as an encoder configuration.

How to check the traffic-rule discrepancy
Contabo’s older post, published September 4, 2024 and last updated April 10, 2025, describes fixed traffic tiers and says that exceeding a package’s traffic for ten consecutive days can result in a reduced port speed. It lists tiers of 10 TB, 32 TB, 81 TB, 162 TB, 243 TB, and 324 TB. The current Help Center instead describes no default bandwidth limit and discretionary fair-use throttling for exceptionally high or disruptive usage, without repeating that schedule. Do not treat the older ten-day threshold or its tiers as a universal current rule for every VPS. The terms attached to your specific product and written confirmation from Contabo support are the relevant checks for your account. Contabo: Rules for Traffic With Contabo
Preflight checklist and common problems
Before starting a continuous stream
- Read the plan terms: Record the plan, region, port rate, traffic wording, and any account-specific confirmation from Contabo.
- Set YouTube’s encoder target: Choose the bitrate for the intended codec, resolution, and frame rate using YouTube’s current guidance; include audio in the total rate.
- Test the actual route: Run an upload test from the VPS and perform a private or otherwise appropriate stream check before depending on it continuously.
- Watch YouTube stream health: Monitor for bitrate instability, dropped frames, or connection warnings rather than relying only on a generic speed-test result.
- Track accumulated traffic and system load: Estimate the monthly transfer and, if encoding on the VPS, check that the CPU can sustain the encoder workload.
If the stream is unstable or throttled
- Available upload rate is too low or fluctuating: Reduce the encoder bitrate or resolution, investigate packet loss and route quality, and test again. Leave room between the target and the connection’s observed sustainable rate.
- Bitrate fits the advertised port rate but YouTube reports poor health: Treat the route, congestion, packet loss, and shared-resource conditions as separate issues; the port specification does not guarantee end-to-end delivery. Re-test at a lower bitrate and ask the provider about the affected route or plan.
- Stream degrades after sustained high traffic: Review the current plan terms and contact Contabo support with your plan, region, traffic pattern, and timestamps. Do not assume the older ten-day schedule applies to your present product.
- CPU is saturated while network rate looks adequate: If the VPS is encoding, reduce encoding complexity or move encoding to another machine; network bandwidth does not compensate for insufficient compute capacity.
Or let it run in the cloud
If the goal is a YouTube channel that loops uploaded recordings continuously, StreamNeo is a cloud alternative to managing a VPS: upload a recording or build a playlist, add your YouTube stream key once, and go live. Nothing has to stay on at home; the uploaded video streams as made, up to 4K 60fps, at one flat price per slot; StreamNeo automatically recovers if YouTube drops the stream. It offers one free day per account with no card required. Monthly: $9.99 per month. Start the free day with StreamNeo.
