ALL INFORMATION WITHOUT WARANTY 2025 BY AI
Great, I’ll look into colocation providers in Berlin (or nearby) that can host a 4HE server with at least 1 GBit/s bandwidth, good peering to O2/Telefonica, and minimal extras. I’ll compare options based on monthly cost, bandwidth, IPv4/IPv6 support, power allowance (including your 600W peak), and whether you can physically visit the facility.
I’ll include a table to make comparison easy and will highlight any notable differences in features or pricing.
The table below compares several low-cost colocation providers in Berlin (and vicinity) that support a 4U (4HE) server. All options include at least a 1 Gbit/s network port and meet the basic requirements (single PSU feed, ~350 W average / 600 W peak power, at least 1× IPv4 and 1× IPv6). Prices are ranked from lowest to higher monthly cost, and notes are provided about peering with O2/Telefonica (usually via BCIX/DE-CIX) and on-site access policies:
| Provider | Location | Monthly Cost | Setup Fees | Bandwidth & Traffic | IPv4/IPv6 | Power Allowance | Peering (O2/Telefonica) | On-site Access | Notes |
|---|---|---|---|---|---|---|---|---|---|

| Speedbone | Berlin (Tempelhof – Alboinkontor) | €149/mo for 4U (Speedbone | Server Housing) (includes 100 W power) – higher power usage incurs extra fees. | €120 one-time (Speedbone | Server Housing) | 1 Gbit port, 1 TB traffic included (Speedbone | Server Housing). Additional traffic above 1 TB can be purchased or capped (unmetered upgrades available on request). | IPv4: allocation per RIPE policy (≥1 included) (Speedbone | Server Housing); IPv6 ready (assign /64 or more on request). | 100 W included (Speedbone | Server Housing); extra power billed per additional 0.1 kW (user’s ~350 W will add cost – expect total ~€200/mo). 100% renewable energy. Redundant power feed available (data center has dual UPS rails). | Top-tier peering – on-site at BCIX/ECIX/DE-CIX. Directly one hop from Telefonica (O2) and major carriers (Speedbone | Peering). Low latency to all German networks. | 24/7 access on request – facility is staffed 24/7; clients can arrange visits (secured racks). Remote hands support available. | 1-month term. Professional data center with robust connectivity. Good value for reliable network, though power over 100 W is extra. Full racks and private cages also available for scaling up. | | Deltaphon | Berlin (2× Data Centers) | €299/mo (CoLocation, Serverhousing, Rechenzentrum | Berlin) (“Enterprise” plan) for up to 4U. All-inclusive pricing. | €69 one-time (CoLocation, Serverhousing, Rechenzentrum | Berlin) | 1 Gbit port, Unmetered traffic (flat rate) (CoLocation, Serverhousing, Rechenzentrum | Berlin) – no overage fees. | 24× IPv4 addresses included (CoLocation, Serverhousing, Rechenzentrum | Berlin); “3000” IPv6 (large allocation) included. | 1200 W power included (max draw) (CoLocation, Serverhousing, Rechenzentrum | Berlin); power flat-rate (no usage billing) (CoLocation, Serverhousing, Rechenzentrum | Berlin). Redundant power and cooling are standard. | Multi-homed backbone – redundant uplinks via high-availability network. Likely connected to exchanges (not explicitly listed) for O2 peering; transit to all major ISPs. | By appointment (standard business hours, 24/7 possible for emergencies). Remote reboot/KVM available as €9.98/mo add-on (CoLocation, Serverhousing, Rechenzentrum | Berlin). | 1-month term. Highest cost, but truly unlimited power and bandwidth – suitable if you need ~1 Gbps flat traffic or a very high-power server. Established local provider (since 1997). Uses 100% green power. |
Summary: For a single 4U server, the lowest monthly cost comes from Hosting Base (around €110) and ScaleUp (~€116), assuming ~350 W power and moderate traffic, closely followed by FlixHost (~€120–€130 with power) – these options have the lowest base fees. Speedbone and IN-Berlin e.V. end up around ~€200/month once sufficient power is included, but offer excellent connectivity (IN-Berlin is non-profit, if eligible). Deltaphon provides a power/traffic-unlimited package at a much higher price (€299). All listed providers are in Berlin and allow the user to visit the hardware in person (with varying ease of 24/7 access). When prioritizing cost, Hosting Base, ScaleUp, or FlixHost are ideal starting points due to their low monthly fees, while Speedbone and IN-Berlin offer strong networking and peering advantages for a moderate price. Deltaphon, although expensive, might be justified for its all-inclusive resources in specific scenarios. Each provider can accommodate a 4U chassis and meets the basic requirements; the final choice may depend on the user’s exact budget vs. needs (e.g. expected bandwidth usage and whether a truly unmetered or high-power solution is required).
