Network uptime

Uninterrupted internet starts at the backbone

LETO IP Transit delivers full BGP routing over a multi-homed backbone interconnected with multiple Tier 1 carriers. If one path fails, traffic instantly reroutes through another — your service stays online.

Multi-homed backbone

Directly interconnected with multiple Tier 1 carriers — traffic reroutes automatically on a single-path failure.

Low domestic latency

Direct peering with major IXs and carriers delivers single-digit millisecond response.

Global reach

Optimal paths to overseas regions including Japan and the US.

Domestic IP Transit

Direct peering with major domestic IXs and carriers (KT, LG U+, SKB) delivers single-digit millisecond latency and stable throughput to local users — your response times feel different.

  • Direct peering with major domestic IXs & carriers
  • Single-digit millisecond latency
  • Cost-optimized domestic traffic

Overseas IP Transit

Interconnects with global Tier 1 carriers to route overseas traffic (Japan, US, etc.) over optimal paths — consistent quality for international customers and global services.

  • Multiple global Tier 1 upstreams
  • Optimal paths to key regions (JP, US, etc.)
  • Automatic rerouting around congestion

Uncompromising network reliability

We continuously check real-time metrics so traffic always takes the best path, and reroute automatically when congestion is detected.

A redundant backbone and multiple upstreams keep you online through single-link failures.

Integrates with the DDoS Clean Zone to absorb large attacks and shield your origin server.
