Why Sofia is a regional peering hub
Sofia stands out in the Balkans for dense IX and carrier presence. At facilities such as TELEPOINT Sofia Centre, networks like Belcloud (AS44901) and ZET.NET (AS6204) maintain active interconnect and exchange ports. Combined with Atlantis and RETN paths, these links on KuzeyDC AS62425 move Istanbul customer traffic closer to regional content and hosting ecosystems—not only large Tier-1 transit.
Belcloud (AS44901)
Belcloud offers a premium IP transit, cloud and content-oriented profile, with a broad Sofia/Europe facility footprint and known interconnect history in Istanbul (e.g. PremierDC). For KuzeyDC, Belcloud provides:
- Alternate paths to regional content and cloud egress
- Complementary capacity if RETN/Atlantis are impaired
- Aligned IPv4/IPv6 dual-stack announcements
ZET.NET (AS6204)
ZET.NET appears with high-capacity ports in Sofia (TELEPOINT Centre/East) and major European exchanges. Presence on BIX.BG, 1-IX EU, DE-CIX and similar platforms acts as a multiplier into European peering via Sofia. On the KuzeyDC backbone, ZET:
- Increases indirect options into IX ecosystems
- Diversifies AS-paths for Balkan and Central European targets
- Adds policy flexibility for abuse/DDoS scenarios
Atlantis + RETN + Belcloud + ZET together
No single operator is a perfect path. Good design chooses by destination and failure mode:
- Atlantis: Balkan corridor and new capacity
- RETN: high-capacity European backbone transit
- Belcloud / ZET: regional content, hosting and IX adjacency
These four paths make KuzeyDC’s carrier-neutral Networking promise concrete: customer traffic is not locked to one Sofia or Frankfurt egress. For peering, cross-connect or community customization, use the Networking page or sales/NOC channels.
