S3c.bg Review 2026. Is s3c.bg good or bad on providing Data Center services?

📄 Editorial Review

(3*) 🔧 Services: Data Center
S3 Company / S3 Data Center is a Bulgarian infrastructure provider based in Sofia, with a business profile centered on data center services, colocation, IP connectivity, DDoS protection and managed infrastructure support. Their infrastructure background goes back to 2010, when the company worked with physical and virtual servers hosted across different European data centers. In 2018, they built their first own data center in Bulgaria, which became the foundation for a stronger local and regional infrastructure business.

S3 Company is not a classic low-cost shared hosting provider. They are better understood as a colocation and network infrastructure company, suitable for businesses, telecom operators, ISPs, streaming providers, cloud platforms, hosting companies, enterprises and resellers that need physical hosting space, professional connectivity and technical assistance in Bulgaria.

Their service range includes Server Colocation, Rack Colocation, Satellite Dish Colocation, IP Transit, Carrier Connect, Remote IX, Cross-Connect Services, DDoS Protection, LIR Services, ASN registration, IP address leasing, hardware support, and data center transfer.

The core hosting-related service is server colocation, available for 1U, 2U, and custom deployments. These services include rack space, reserved power, precision cooling, internet connectivity, DDoS protection, IP addresses, a free IPMI / OOB management port, private VLAN between customer equipment, optional BGP session with AS44901, remote hands, free initial installation and access to a spare-parts warehouse inside the data center.

For larger infrastructure needs, rack colocation is available as 48U full rack, 22U half rack, and 11U quarter rack. These options include individual power metering, shared Premium IP Transit, IPv4/IPv6 addressing, optional BGP session, a white-label management panel, 24/7 data center access, remote hands and eyes, and connectivity options to another data center in Sofia.

A distinctive part of their portfolio is satellite dish colocation, suitable for IPTV providers, content distribution networks, OTT TV platforms, video-on-demand providers, digital service companies and video backhaul projects. This service includes an antenna field, anti-icing system, proactive signal monitoring, coaxial or optical LNB options, satellite equipment space and 24/7 remote hands on site.

Their connectivity portfolio is one of the strongest parts of the company. Global IP Transit includes guaranteed capacity, no overselling, Nx100 Gbps global capacity, redundant MPLS mesh networking, IPv4/IPv6 dual-stack support, BGP communities, RPKI-based origin validation, jumbo frames, link aggregation options and carrier-grade SLA positioning. Carrier Connect gives customers access to Tier 1 carriers, ISPs, local networks, L2 transport providers, dark fiber and direct provider connectivity. Remote IX allows connection to Internet Exchanges across Europe, including DE-CIX, AMS-IX, LINX, BIX.BG, GR-IX / gr-ix.gr, InterLAN-IX / interlan.ro, Equinix IX, VarnaIX / varnaix.net and others.

Their managed services are practical and infrastructure-oriented. LIR Services cover IPv4/IPv6 rental or purchase, autonomous system registration, RIPE Database resource management, RPKI setup, rDNS, IP reputation monitoring and resource sponsorship. Data Center Transfer helps companies migrate servers, switches and routers from another European facility to S3 Data Center. Hardware Support and Equipment includes diagnostics, component replacement, equipment rental or purchase, lease-to-own options, buy-back, server/network component supply and 24/7 technical help.

The website is available in English and Bulgarian, while pricing is listed in EUR and BGN. This makes S3 Company practical for both Bulgarian customers and international infrastructure buyers looking for a Sofia-based presence.

💰 Price & Cost

The clearest pricing is available for server colocation. The 1U plan starts at 49 EUR / 95.84 BGN per month, while the 2U plan starts at 59 EUR / 115.39 BGN per month. Custom-size colocation is available on request.

These colocation plans include a free one-month test period, 0.5 Amp power at 230V, precision cooling, shared 1 Gbps Premium IP Transit, free DDoS protection, one IPv4 address plus IPv6 allocation, free IPMI/OOB management port, 30 minutes of remote hands and eyes support, free initial installation and configuration, and 24/7 data center access.

Optional services include a BGP session with AS44901 at 25 EUR / 48.90 BGN per month and cross-connect to another member at 15 EUR / 29.34 BGN per month. Annual prepayment gives a 10% discount, and customers colocating more than one server may receive additional discount conditions.

Rack colocation is available in 48U, 22U, and 11U formats, with full-rack, half-rack and quarter-rack options. These plans are better treated as custom infrastructure offers, because power, bandwidth, cross-connects, BGP, remote hands and private requirements can vary significantly from one deployment to another.

A confirmed payment-method list is not available, so payment options should not be assumed. The strongest commercial advantage is the free 30-day non-binding test period, especially for companies that want to test a Sofia colocation footprint before committing long term.

🏢 Data Center

S3 Company operates from Sofia, Bulgaria, at 63 Shipchenski prohod Blvd., with its own S3 Data Center infrastructure. The facility follows a TIER III design approach and works as a carrier-neutral data center.

The infrastructure includes three colocation rooms with more than 7000U of operating equipment, high-quality 48U cabinets, 50 cm raised floor, individual online power meters, Zero-U PDU options, private cells / colocation halls, and support for high-density deployments up to 12 kW per cabinet. The facility is positioned close to Sofia’s telecom ecosystem and supports connectivity to other data centers in the city.

Power architecture includes supply from two independent substations, separate substations with 2 x 1000 kVA transformers, a reserved 1000 kVA diesel generator (N+1), modular redundant UPS systems, separate A+B electrical panels and smart monitoring. Cooling uses N+1 high-efficiency precision air conditioning, hot/cold zones, free cooling, indirect adiabatic cooling, spare HVAC parts and continuous temperature / humidity monitoring.

Security includes video surveillance, NFC access control, 24/7 physical security, fire detection, authorized 24-hour customer access and individual cabinet locks. The data center SLA is 99.99%, which is an important reliability marker for colocation and network customers.

Connectivity is a major advantage. S3 Company offers Carrier Connect, Remote IX, IP Transit, cross-connects, DWDM connectivity to other data centers, access to local telecom operators and a strong carrier / Internet Exchange ecosystem. Their network options include BGP sessions with AS44901.

The company expanded international capacity with a 100G port to Hurricane Electric in Sofia in January 2026, strengthening low-latency connectivity, scalability and backbone redundancy.

Recognized carriers, IXs and network partners connected with their ecosystem include Hurricane Electric, Arelion, Lumen, Cogent, GTT, NTT Communications, RETN, Tata Communications, TI Sparkle, Vodafone, A1, Vivacom, BIX.BG, DE-CIX, AMS-IX, LINX, Equinix IX, GR-IX, InterLAN-IX, VarnaIX, TurkIX and others.

✍️ Customer Support

Customer support is one of S3 Company’s strongest operational points. Technical support is available 24/7/365 by phone and email. Sales support works Monday to Friday, from 9:00 to 18:00.

Support is not limited to basic ticket handling. Their technical assistance includes remote hands and eyes, hardware diagnostics, component replacement, spare-parts access, equipment installation, initial software configuration, data center migration planning, server cleaning, cabling, rack installation and full inspection after relocation.

For businesses running physical infrastructure, this is a practical advantage. Many infrastructure incidents happen outside normal business hours, and S3 Company’s on-site engineering support, spare-parts availability and repair capability reduce the operational risk for customers that do not maintain their own hardware team in Sofia.

🔨 Control Panel

S3 Company uses a custom infrastructure-management approach rather than a mass-market shared hosting panel such as cPanel or Plesk. Server colocation customers receive a free custom panel for secure connection to IPMI / KVM and remote server control.

The panel can also be used in a white-label model, allowing resellers to manage services under their own brand. Useful functions include management-port access, network usage viewing, server details and white-label client panel options. This fits their target market well: infrastructure users, resellers, ISPs and hosting companies rather than entry-level website owners.

For LIR and network customers, the management layer is more operational than traditional web-hosting oriented, with services around RIPE resources, BGP sessions, IP address management, rDNS, RPKI, route objects and network monitoring.

🎯 Conclusion

S3 Company is a strong choice for customers who need professional Bulgarian colocation, carrier-neutral data center space, IP Transit, BGP connectivity, DDoS protection, remote hands, hardware support and network-oriented managed services. Their biggest strengths are the Sofia data center location, TIER III-oriented infrastructure, 99.99% SLA, 24/7 NOC support, spare-parts warehouse, strong carrier ecosystem, AS44901 BGP options, and the practical one-month free test period for selected infrastructure services.

This is not the best match for someone looking for a simple shared hosting account, beginner website builder or cheap WordPress hosting plan. It is much better suited to companies that already understand infrastructure requirements or need a reliable physical and network presence in Bulgaria. For hosting providers, telecom operators, streaming companies, resellers, enterprises and businesses that need serious network control, S3 Company is a credible and technically mature option.
