Dedicated Internet Leased Line for
Mission-Critical Business

An Internet Leased Line (ILL) is a dedicated, fixed-bandwidth internet circuit delivered exclusively to one organisation. Unlike broadband, the bandwidth is not shared with other users, upload and download speeds are symmetrical, and performance is guaranteed under a commercial SLA. Enterprises use leased lines for mission-critical applications, cloud workloads, VoIP and multi-branch connectivity.

Broadband is a shared, contended service with asymmetric speeds, dynamic IPs and best-effort support. An Internet Leased Line is uncontended and dedicated 1:1 to your business, with symmetrical bandwidth, static IP addresses, low and stable latency, and a 99.95% uptime SLA backed by defined repair times.

Businesses need leased lines when downtime or congestion has a direct cost: cloud and SaaS applications, video conferencing, VoIP telephony, VPNs, ERP systems and customer-facing services all depend on consistent bandwidth and latency. A dedicated internet connection with an SLA turns connectivity from a variable risk into a predictable utility.

Symmetrical bandwidth means upload and download speeds are identical: a 100 Mbps leased line delivers 100 Mbps in both directions. This matters for cloud backups, video calls, VoIP, remote access and any workload that pushes data out of your network, where asymmetric broadband upload speeds become the bottleneck.

A Service Level Agreement (SLA) is a contractual commitment covering uptime (typically 99.5%–99.95%), mean time to repair, latency, packet loss and jitter. If the service misses those thresholds, service credits apply. Cylentrix Internet Leased Lines carry a 99.95% uptime SLA monitored 24×7 by our NOC.

Leased line bandwidth is provisioned 1:1 on dedicated fiber from the carrier's core to your premises, so there is no contention ratio and no sharing with other subscribers. Capacity is reserved end to end, and AI-assisted NOC monitoring continuously verifies throughput, latency and packet loss against the committed rate.

Yes. Leased lines scale from 10 Mbps to 1 Gbps and beyond on the same fiber in most cases. Because the last mile is fiber, upgrades are usually a configuration change at the carrier end rather than a new installation, and Cylentrix manages the change under the existing SLA.

Yes. Every Cylentrix Internet Leased Line includes static public IP addressing, typically a /30 to /29 block, with larger allocations available on justification. Static IPs enable hosting, VPN termination, email servers, CCTV access and any service that requires a fixed public address.

Yes. Cylentrix designs BGP-enabled leased line deployments with provider-independent or provider-assigned address space, dual-carrier multi-homing and automatic failover, so your network stays reachable even if one upstream carrier fails.

Yes. Branches can be connected using leased lines at each site combined with MPLS, point-to-point circuits or SD-WAN overlays. Cylentrix designs the WAN as one architecture: dedicated internet at each location, secure inter-branch connectivity, and centralised 24×7 monitoring under one SLA.

Manufacturing, healthcare, BFSI, IT/ITES, education, retail, logistics, government, data centers and hospitality all depend on leased lines: anywhere ERP, telemedicine, trading, cloud development, e-learning, POS billing, tracking systems, citizen services or guest connectivity cannot tolerate contention or downtime.

Typical delivery is 2–4 weeks depending on fiber availability at the site. Where fiber already reaches the building, commissioning can complete in days. Cylentrix's carrier-neutral model lets us select the operator with the fastest feasible last mile at each location, and we manage feasibility, installation and testing end to end.
