Business Internet: A Guide to Guaranteed B2B Connectivity for Companies in 2026

Business internet — guaranteed symmetrical connectivity with defined availability, dedicated capacity, and contractual operator responsibility — is in 2026 a fundamental operational infrastructure for every company dependent on cloud applications, VoIP telephony, remote employee access, or data transfer between branches. New Telekom s.r.o. operates its own backbone network built on Juniper technology with direct peering at NIX.CZ (Neutral Internet eXchange in Prague) and international interconnection to Frankfurt — and has been delivering guaranteed symmetrical business internet to companies of all sizes throughout the Czech Republic since 2000.

What is business internet and how does it differ from commercial connections?

The difference between business internet and standard commercial or home connections is not just in price — it is in architecture, guarantees, and operator responsibility. Commercial connections (retail tariffs, cable internet, standard VDSL) are designed as shared services: capacity is aggregated — tens or hundreds of customers share the same transmission segment, so actual speed depends on current network load. Availability is not contractually guaranteed, speeds are asymmetric (high download, low upload), and during outages standard conditions apply without defined repair times. Business B2B internet from New Telekom is built on different principles:

• Dedicated 1:1 capacity — the allocated transmission speed is available at full capacity at all times, independent of the load from other customers
• Symmetric download and upload — identical speed in both directions, critical for VoIP, video conferencing, cloud backups, VPN tunnels, and production documentation transfer
• 99.9% SLA availability — contractually guaranteed availability with defined outage response time and repair time
• Direct peering at NIX.CZ — traffic to Czech servers and content goes directly through NIX.CZ in Prague without unnecessary transit hops; resulting latency to Czech destinations typically below 2 ms
• Static IPv4 addresses — fixed public IP address for operating VPN servers, SIP registrations, or mail servers
• 24/7 technical support — dedicated New Telekom NOC team with guaranteed response time

What types of business internet connections does New Telekom offer?

FTTO — Fiber to the Office

FTTO (Fiber to the Office) is the premium business internet standard in 2026 — fiber optic cable physically brought directly to the customer's office or production space. No metallic section on the last mile, no transmission speed limitation by copper cable, no sensitivity to electromagnetic interference from industrial machinery or transformers. New Telekom builds and operates its own fiber infrastructure throughout Prague and in other locations in the Czech Republic — direct backbone routes in Prague 1, Prague 2, Prague 4, Prague 5, Prague 7, Prague 8, and other districts, distribution nodes connected to the Juniper backbone network with direct access to NIX.CZ. A FTTO connection from New Telekom typically includes:

• A dedicated OS2 Single-Mode fiber pair from the distribution node to the customer
• Certification measurement of each fiber route (OTDR, attenuation below ČSN EN 50346 standard)
• Termination with LC/APC or LC/UPC connectors in the customer's data rack
• An active element (media converter or SFP+ port on the customer's router) for conversion to electrical Ethernet

Available speeds: 100 Mbit/s, 500 Mbit/s, 1 Gbit/s, 10 Gbit/s symmetrical — with the possibility of increase without physical intervention in the cabling.

Ethernet via backbone network — for longer distances

For customers beyond the reach of New Telekom's own fiber network, we provide business internet through a partner network covering the entire Czech Republic — always with the same SLA guarantees and the same New Telekom NOC monitoring, regardless of which physical transmission segment is used on the last mile.

Backup connection — LTE-A Pro and 5G via eSIM

Every business internet connection from New Telekom can be supplemented with backup mobile connectivity via eSIM with eUICC — a global SIM card managed remotely without physical replacement. The backup connection using LTE-A Pro (bands B1/B3/B7) or 5G technology activates automatically during primary connection outage — switching within 10 seconds via SD-WAN logic. The customer experiences a brief interruption, and traffic resumes without manual intervention.

What parameters should business internet meet?

For IT managers and procurement professionals comparing business internet offers, it is crucial to distinguish between nominal and guaranteed parameters. Here is a list of parameters that a business B2B internet contract should include:

Why does direct peering at NIX.CZ matter?

NIX.CZ (Neutral Internet eXchange) is a neutral internet exchange point in Prague where direct Czech and international operators exchange traffic without passing through transit networks. New Telekom is a direct member of NIX.CZ — resulting latency to Czech servers, streaming services, cloud environments with a region in Prague, and other local content is below 2 ms. Operators without direct membership at NIX.CZ must route traffic through a transit partner — typically via a node in Germany or another country — and back. The resulting latency is 10–30 ms even for domestic content. For applications such as VoIP, video conferencing, real-time database queries, or latency-sensitive SaaS systems, this difference is visible. For customers with cloud environments in Microsoft Azure region West Europe or AWS eu-central-1 (Frankfurt), New Telekom provides direct interconnection to Frankfurt with latency below 10 ms — without passing through uncontrolled transit nodes.

How does business internet integrate with other New Telekom services?

Business B2B internet is the fundamental layer upon which New Telekom builds complex network architectures — and it naturally combines with other services: MPLS VPN and branch connectivity: On the same physical FTTO connection, business internet and a dedicated private MPLS VPN link to another branch or data center can be operated simultaneously — as logically separate VRF instances on the router. The customer pays for one physical connection but has two independent networks. CloudConnect — private cloud link: For customers accessing Microsoft Azure, AWS, or Google Cloud via business internet, the natural next step is to migrate to a CloudConnect private circuit — elimination of public internet traversal, reduction of Azure egress costs by 40–50%, and guaranteed latency to the cloud. VoIP and SIP Trunk: A business VoIP telephone system — SIP Trunk, virtual PBX, or WebRTC — works reliably only on a connection with guaranteed latency and QoS prioritization of voice traffic (EF DSCP). New Telekom business internet natively supports this prioritization. IT security: A business connection without appropriate security architecture is an open gateway. New Telekom's IT security solutions — Fortinet FortiGate NGFW, Zero Trust Network Access (ZTNA), NIS2 compliance consulting — naturally build upon the network infrastructure.

For which types of companies is New Telekom business internet most suitable?

Business B2B internet from New Telekom is suitable for any organization that needs connectivity with guaranteed parameters. The most common customers: Manufacturing companies — operate SCADA systems, ERP (SAP, Microsoft Dynamics) and transfer production documentation and CAD files. Symmetrical upload and guaranteed availability are prerequisites for uninterrupted production operations. Technology companies and SaaS operators — daily access cloud environments (Azure, AWS, GCP), operate development and production environments, and need consistent low latency for development tools and CI/CD pipelines. Financial institutions and insurance companies — are subject to DORA (EU Regulation 2022/2554) and require auditable network architecture with demonstrable availability and security measures. Law firms, consulting firms, and accounting houses — work with sensitive client data in cloud DMS systems and need guaranteed connectivity with SLA and static IP addresses for VPN access. Logistics and e-commerce platforms — transfer large volumes of data between their own infrastructure and the cloud, operate API integrations with partners, and need symmetrical connectivity for uploading data feeds and customer exports. Healthcare facilities and laboratories — operate imaging systems (PACS, DICOM) and electronic health records (EHR) with high demands on transfer capacity and availability under NIS2 regulation. Office complexes and multi-tenant buildings — building managers and developers in Prague and other cities in the Czech Republic who want to offer enterprise connectivity to tenants as part of the building's standard equipment.

How does business internet activation from New Telekom work?

The process from first contact to functional connection is structured and predictable: 1. Location survey and route design (1–2 weeks): The New Telekom team verifies backbone route availability at the customer's location, designs the physical last mile connection route, and prepares a technical specification including redundancy design. 2. Offer and contract (1 week): The customer receives a price quote with precisely defined SLA parameters — availability, response time, repair time, and backup connectivity parameters. No hidden conditions. 3. Physical connection implementation (2–4 weeks): Laying or using existing fiber routes, installation of active elements, certification measurement. 4. Testing and handover (1 week): Latency, throughput, and availability measurement. Handover of technical documentation suitable for security audits. Activation of monitoring in the New Telekom NOC system. 5. Operation and ongoing management: Continuous 24/7 monitoring, proactive anomaly notifications, customer has direct contact to the New Telekom technical team. Total time from contract signing to functional business internet: typically 3–6 weeks depending on location and scope of implementation.

Frequently asked questions about business internet

What is the minimum guaranteed speed of New Telekom business internet?

New Telekom delivers business B2B internet from 100 Mbit/s symmetrical — this speed is fully sufficient for an office with 10–30 users using cloud applications, Microsoft 365, VoIP, and video conferencing. For manufacturing plants, data centers, or e-commerce platforms with high data volumes, we deliver 500 Mbit/s, 1 Gbit/s, and 10 Gbit/s symmetrical connections. Capacity can be increased after activation without physical intervention in the cabling.

Does New Telekom cover locations outside Prague with business internet?

Yes. New Telekom's own backbone network covers Prague and surrounding areas — Prague 1 to Prague 22, the Central Bohemian Region, and selected industrial zones. For other locations in the Czech Republic, New Telekom provides business internet through a partner network, always with the same SLA guarantees and the same 24/7 New Telekom NOC monitoring. Verification of availability for a specific address is part of the free location survey at coverage.

What happens during a business internet outage?

The New Telekom NOC detects an outage within 2 minutes of occurrence through continuous monitoring. The customer is automatically notified and a technician begins diagnostics. Guaranteed response time is within 15 minutes, guaranteed repair time (MTTR) is within 4 hours for critical outages. If SLA is not met, the customer is entitled to a discount credit according to the contract. Customers with backup LTE-A Pro connectivity have traffic automatically switched to backup within 10 seconds of primary connection outage — without manual intervention.

Is it possible to have both business internet and MPLS VPN for branches on a single connection?

Yes — and it is a standard configuration for New Telekom customers with multiple locations. On a single physical FTTO connection, we operate business internet and an MPLS VPN circuit as logically separate VRF instances on the router. Traffic is strictly isolated — an outage or overload in the internet layer does not affect MPLS VPN traffic and vice versa. The customer pays for one physical connection.

Does New Telekom business internet support IPv6?

Yes. All New Telekom business connections are operated in dual-stack mode — native IPv4 and IPv6 simultaneously. The customer receives an allocated IPv6 /48 prefix for their own use on the internal network. The New Telekom backbone network is fully IPv6 compatible, and the BGP session at NIX.CZ includes exchange of both IPv4 and IPv6 prefixes.

Conclusion

Business internet from New Telekom is not a product for those seeking the cheapest connection — it is infrastructure for companies for whom an internet outage means production interruption, loss of orders, or violation of SLA with their own customers. Guaranteed symmetrical 1:1 capacity, direct peering at NIX.CZ, 99.9% SLA with 15-minute response time, and 24/7 New Telekom NOC monitoring are parameters we have considered standard for 25 years of operation — not a premium add-on. Verify business internet availability at your address on the coverage page, or contact us via the contact form — we will perform a free location survey and design a connection tailored to your operational requirements.
