How we built a transit network in Frankfurt and Milan

ShadowIP is a network operator with its own autonomous system, AS218995. PoPs are in Velbert, Frankfurt, Milan, Warsaw, Paris, Amsterdam, New York, and Brazil.

Frankfurt and Milan are where the published exchange latencies are measured. From Frankfurt, the published paths are 3 ms to AMS-IX and 2 ms to DE-CIX. From Milan, the published path to MIX-IT is 4 ms. Frankfurt to Milan is 6 ms.

Coverage of LINX and smaller exchanges is part of the same description. A separate latency is not published for the other PoPs.

Upstreams are multi-homed, so the network is not tied to a single upstream. Prefixes are validated automatically. IPv6 is native from day one. Bandwidth is described as unmetered on every tier.

The free tier and the paid tiers sit on this same network. What changes between them is port speed, the number of BGP sessions, and what each plan lists.
