Speedify Combines Starlink and Speedcast Internet for Faster Upload and Download Speeds

For network engineers, IT managers, and infrastructure decision-makers, Speedify's Starlink and Speedcast bonding delivers concrete operational value:

• Redundancy without identical failure modes: Starlink and Speedcast fail for different reasons. LEO satellite handoffs, weather attenuation at Starlink's frequencies, and orbital congestion do not cause the same disruptions as Speedcast signal degradation. Speedify exploits this difference to maintain a healthy path even when one connection is disrupted.
• Combined internet upload and download capacity across both connections: Without bonding software, devices use one connection at a time. With Speedify, both connections carry traffic simultaneously, letting your team approach the combined throughput of Starlink and Speedcast rather than being capped at whichever connection is active at a given moment.
• Latency-aware traffic distribution: Speedify routes interactive, latency-sensitive traffic over Starlink's LEO connection and uses the Speedcast connection for background throughput. Speedify adjusts distribution in real time based on measured latency, packet loss, and jitter every few milliseconds.
• Seamless failover with no session interruption: When Starlink drops or degrades, active VoIP calls, video conference sessions, and cloud application sessions continue without interruption. Speedify reroutes at the packet level before applications detect a problem. When Starlink recovers, Speedify rebalances automatically.
• Uniform AES-256 encryption across all connections: All traffic bonded by Speedify passes through AES-256-GCM encrypted tunnels using DTLS 1.2. Every packet is protected regardless of which connection carries it. See Speedify's full encryption specifications for detail.
• Centralized policy and monitoring across your team: Speedify Teams provides a single dashboard for managing connection priorities, applying data limits to metered capacity, and monitoring real-time usage across all team devices and locations.

Starlink operates in low-Earth orbit (LEO), with satellites positioned approximately 340 miles above Earth. This results in round-trip latency in the 25 to 60 millisecond range and upload and download speeds of 100 to 300 Mbps under good conditions. Starlink's LEO position makes it well-suited for real-time applications: VoIP, video conferencing, live data transmission, and interactive cloud applications. However, because LEO satellites move relative to the ground, Starlink dishes experience brief micro-outages during satellite handoffs, and signal quality can degrade under heavy rain or snow.

Speedcast is a managed satellite and network communications provider serving maritime, energy, cruise, government, and remote enterprise customers across more than 140 countries. Speedcast delivers connectivity over a multi-orbit, multi-band network that includes GEO Ku-band, Ka-band, C-band, and L-band capacity sourced from multiple satellite operators, plus integration with 4G/5G cellular and terrestrial circuits. For maritime and offshore energy customers, Speedcast manages multi-link connectivity environments where GEO satellite capacity provides primary high-bandwidth throughput and additional connections serve as redundancy or latency-optimized overlay. GEO satellite connections in Speedcast-managed environments carry round-trip latency exceeding 600 milliseconds on GEO paths, making latency-sensitive applications dependent on any lower-latency connection in the bundle. Adding Starlink to a Speedcast-managed environment and bonding it with Speedify gives network administrators packet-level traffic distribution and seamless failover across all paths simultaneously.

Speedify bonds both connections into a single managed internet path. All traffic passes through one Speedify encrypted tunnel. Inside that tunnel, Speedify distributes packets across Starlink, the Speedcast connection, and any additional internet connections, including 4G/5G cellular and wired Ethernet, based on real-time performance measurements. Latency-sensitive packets are preferentially routed over Starlink. When Starlink degrades, Speedify immediately shifts affected traffic to the Speedcast connection. When Starlink recovers, Speedify rebalances across both connections automatically. Your team never manually switches connections, and no active session is interrupted.
