New Atlantis Interconnect: Balkan Corridor on AS62425

2 min read 2 reads 3 questions answered

Why add a new Atlantis interconnect?

On a carrier-neutral backbone, depending on a single international egress creates both capacity and failure risk. The new Atlantis interconnect on KuzeyDC AS62425 adds another physical/logical path alongside existing local and global transit options, diversifying Istanbul-origin traffic toward the Balkans and Central Europe.

The Atlantis session is provisioned with the same security discipline—prefix filtering, RPKI validation and max-prefix limits. The goal is not “more ASNs,” but measurable gains in latency, jitter and failover time.

What the Istanbul–Sofia corridor unlocks

Bulgaria is a natural network bridge between Turkey and Central Europe. Dense interconnect facilities in Sofia (e.g. TELEPOINT and regional exchanges) create alternate paths to European destinations. Steering KuzeyDC customer traffic carefully over the Atlantis path:

  • Reduces dependence on global transit alone (e.g. Cogent / RETN)
  • Provides a second Balkan egress during maintenance or outages
  • Enables shorter AS-paths to regional content and hosting networks

BGP and traffic engineering

Community policies define destination-aware preferences. Domestic CDN/peering priority (Cloudflare, Google, Meta) is preserved, while Balkan and Eastern European targets can be weighted toward Atlantis based on measurements.

  1. Track Sofia and European PoP RTT with synthetic probes
  2. Validate prefixes that shift to Atlantis during failover drills
  3. Report capacity with peak / 95th-percentile utilization

Result: colocation, dedicated and cloud customers gain a more resilient Balkan egress without single-carrier lock-in. For peering or cross-connect requests, use the Networking page or contact NOC.

Frequently Asked Questions

3 questions answered
Is the Atlantis path available to all customers?

Yes. It applies under the standard AS62425 routing policy for carrier-neutral facility customers; custom community requests are reviewed with NOC.

Does Atlantis egress via Sofia?

It is positioned to strengthen the Balkan corridor and is evaluated together with Sofia’s interconnect ecosystem (RETN, Belcloud, ZET and regional IXes).

Are Cogent/RETN sessions being removed?

No. Atlantis is an additional path; the multi-upstream model remains.
