Portfolio
123NET Business Services
Fiber, fixed wireless, DIA, dark fiber, Ethernet, MPLS, SD-WAN, UCaaS, DDoS protection, Smart Hands, colocation, and Internet Exchange — all on 123NET's owned Michigan infrastructure.
Fiber Internet — 4,500+ Miles, Up to 400 Gbps
123NET owns and operates 4,500+ miles of fiber across Michigan — designed, built, and maintained entirely in-house. Capacity scales to 400 Gbps with 99.99% SLA. On-net installations complete in under 30 days; 270,000+ near-net Michigan addresses are within the buildout footprint. 200 to 300 miles of new fiber added annually ensures the network continues expanding into new Michigan communities.
Fixed Wireless — Up to 10 Gbps, Installs in 7–14 Days
Dedicated fixed wireless connectivity from 55+ towers across Michigan — delivering speeds up to 10 Gbps with 128-bit AES encryption and no buildout costs. Installs in 7 to 14 days, making it the fastest path to dedicated business connectivity for locations outside the direct fiber footprint. Suitable as a primary connection or as a diverse secondary circuit alongside fiber — and used by many Michigan businesses as a bridge while fiber construction is underway.
Dedicated Internet Access (DIA) — 99.99% SLA, BGP, Managed Router
Private, unshared bandwidth with a formal 99.99% uptime SLA — not shared with other customers. DIA includes BGP routing support, a managed router option, and access to 123NET's 12 transit providers for redundant, diverse paths to the internet. Backed by Michigan-based 24/7/365 support with an average phone pickup time of 30 seconds. Available over fiber or fixed wireless.
Dark Fiber — 4,500+ Miles, Lease or IRU
Lease or IRU access to 123NET's owned dark fiber infrastructure across Michigan — supporting Ethernet, SONET, and DWDM protocols. Designed for large enterprises, carriers, healthcare systems, universities, and utilities that need to run their own optical equipment and protocols over a private fiber path. 123NET's in-house engineering and construction capability means route customization and new segment builds are handled by the same team that owns the infrastructure.
Ethernet Services — EPL/EVPL and E-LAN, Up to 100 Gbps
Point-to-point (EPL/EVPL) and any-to-any (E-LAN) Ethernet services up to 100 Gbps over fiber and 10 Gbps over fixed wireless — unmetered, with sub-10ms latency on the 123NET network. Designed for multi-site enterprises, data center interconnect, and campus connectivity that require private, high-bandwidth Layer 2 transport without the overhead of a full MPLS WAN.
MPLS — Private WAN, QoS, 15-Minute SLA
Private MPLS WAN with QoS prioritization, dynamic routing, and a 15-minute SLA response time — available over 123NET fiber or fixed wireless. Purpose-built for enterprises with multiple Michigan locations requiring consistent application performance and traffic segmentation. Integrates with SD-WAN for a hybrid WAN architecture that combines MPLS reliability with cloud-optimized routing.
SD-WAN — Seamless Failover, Zero-Touch Provisioning, Cloud Security
Managed SD-WAN delivering seamless failover, zero-touch provisioning, and global WAN visibility — works over any underlying connection type, including 123NET fiber, fixed wireless, or third-party circuits. Includes cloud security integration and centralized policy management. Appropriate for enterprises running multi-site WAN that need application-aware routing and cloud-direct access without full MPLS dependency.
UCaaS / Unified Communications — VoIP, Video, Chat
Cloud-delivered unified communications covering VoIP, video, chat, CRM integrations, auto attendant, and call recording — delivered over 123NET's own fiber network. The voice path stays on-net and avoids the public internet for Michigan-to-Michigan calls. Designed for businesses that want to consolidate voice and connectivity under a single Michigan provider.
DDoS Protection — Real-Time Mitigation at Network Core
Real-time DDoS detection and mitigation performed at the 123NET network core — scrubbing attack traffic before it reaches customer infrastructure. Includes real-time reporting and 24/7/365 monitoring. Because mitigation happens at the carrier level rather than at customer premises, volumetric attacks that would saturate an on-site appliance are absorbed by 123NET's upstream infrastructure.
Smart Hands Plus — On-Site NOC Technicians, 24/7/365
Physical on-site technician service with a 15-minute priority SLA, available 24/7/365. Covers rack and stack, cabling, hardware swap, asset management, inventory tracking, and logistics coordination. Eliminates the need to maintain on-site IT presence for data center equipment — 123NET's NOC technicians act as an extension of the customer's IT team for physical infrastructure tasks.
Data Center Space & Internet Exchange
Colocation in single cabinets (42U) and half cabinets (21U), private suites, and private cages — housed in Michigan data center facilities on 123NET's owned fiber network. 123NET also operates two Michigan Internet Exchange points: DET-iX (Detroit) and GRR-iX (Grand Rapids), providing low-latency peering for organizations with high in-state traffic volumes. Direct exchange peering reduces latency and transit costs for Michigan-centric traffic.
Additional Services — Wavelengths, SIP, Cloud On-Ramp, Managed Firewall
Wavelengths (optical transport), SIP trunking, PRI, Business Voice, Cloud On-Ramp (direct connectivity to AWS, Azure, Google Cloud), and Managed Firewall — rounding out 123NET's full-stack Michigan connectivity platform. Each service is delivered over 123NET's owned infrastructure with the same 24/7/365 Michigan-based support and SLA commitments as the core connectivity portfolio.

Why 123NET
Key Strengths
What sets 123NET apart from national carriers and Michigan resellers — and where its owned infrastructure makes a difference.
123NET owns every mile of its 4,500+ mile Michigan fiber network — designed, constructed, and maintained in-house. No leased backbone, no third-party carrier for core transport, no dependency on another provider's SLA for your uptime guarantee. Troubleshooting, capacity upgrades, and route modifications are all controlled by the same team that built the network.
123NET's NOC and support teams are Michigan-based — not offshore. The 30-second average phone pickup time reflects the operational commitment to real-time support rather than queued ticketing. For Michigan businesses where a connectivity outage directly impacts operations, local support with carrier-level response times is a meaningful differentiator.
55+ fixed wireless towers across Michigan allow 123NET to deliver dedicated connectivity in 7 to 14 days at locations outside the fiber footprint — with no buildout costs. Speeds up to 10 Gbps with 128-bit AES encryption. For Michigan businesses that need carrier-grade connectivity faster than a fiber build allows, fixed wireless provides an immediate path.
123NET adds 200 to 300 miles of new Michigan fiber annually — expanding near-net coverage and eventually converting near-net addresses to on-net. For businesses currently served by fixed wireless or on the near-net buildout list, the network trajectory means fiber access improves each year without changing providers.
123NET serves the Detroit Pistons, AAA, University of Michigan–Flint, DTE Energy, Henry Ford Health System, Plum Market, and dozens of Fortune 500 companies with Michigan operations. This customer profile — healthcare systems, utilities, universities, and major employers — validates 123NET's capability for demanding enterprise and institutional use cases.
123NET operates the Detroit Internet Exchange (DET-iX) and Grand Rapids Internet Exchange (GRR-iX) — enabling direct peering between networks and reducing latency for Michigan-centric traffic. For organizations with high in-state data volumes, exchange peering lowers transit costs and improves performance compared to routing traffic through out-of-state exchange points.
