Question 1

What is IP Transit and how does Sofia Connect deliver it?

Accepted Answer

IP Transit is a paid service that grants access to the global internet routing table via a carrier's upstream network. Sofia Connect delivers IP Transit from its Sofia-based network under AS47872, peering with 96+ networks at major European and regional Internet Exchange Points. Customers connect at Sofia PoPs (Equinix SO1/SO2, Telepoint) and receive full-table BGP routing with redundant upstream paths, 24/7 NOC monitoring, and a 99.99% SLA backed by financial penalties. Port speeds range from 1G to 400G.

Question 2

What is the latency between Sofia and Frankfurt?

Accepted Answer

The one-way latency between Sofia and Frankfurt on Sofia Connect's network is approximately 24.5 ms. This is achieved via a direct, low-hop-count fiber path between Sofia PoPs (Equinix SO1/SO2) and Frankfurt (Equinix FR5, New Telco), without unnecessary transit through third-party intermediaries. The route supports DWDM wavelengths up to 400G with coherent optics for deterministic, consistent latency profiles.

Question 3

What is the latency between Sofia and Istanbul?

Accepted Answer

The one-way latency between Sofia and Istanbul on Sofia Connect's network is approximately 12 ms. Sofia's geographic proximity to Istanbul makes this one of the most competitive SE-Europe-to-Turkey paths available from a single carrier. Sofia Connect maintains a direct PoP in Istanbul (Equinix IL2), enabling both IP Transit and DWDM wavelength services with this low-latency profile.

Question 4

What is the latency between Sofia and London?

Accepted Answer

The one-way latency between Sofia and London on Sofia Connect's network is approximately 35 ms. The path connects Sofia PoPs to London TH North via a combination of owned infrastructure and strategic peering agreements. DWDM wavelength services are available on this corridor at 100G and 400G capacities, with protected and unprotected options.

Question 5

Does Sofia Connect offer Dark Fiber?

Accepted Answer

Yes. Sofia Connect offers Dark Fiber services within Bulgaria, including Sofia metro and national routes. The infrastructure uses G.652D single-mode fiber, which is compatible with all standard coherent and non-coherent optical systems. Two commercial models are available: a monthly lease (billed per fiber pair per meter) and a 15-year Indefeasible Right of Use (IRU). Both options include 24/7 NOC monitoring and SLA-backed repair commitments. Route surveys and feasibility studies are included in the onboarding process.

Question 6

What DWDM capacities are available from Sofia Connect?

Accepted Answer

Sofia Connect's DWDM service supports wavelength capacities from 10G up to 800G using coherent optics technology. Available wavelengths include 100G and 400G on European routes (Sofia–Frankfurt, Sofia–Istanbul, Sofia–Athens, Sofia–London), with capacity scaling to 800G on select corridors. Routes extend to the Caucasus (Tbilisi, Yerevan, Agarak) and the Middle East (Dubai), making Sofia Connect's DWDM particularly suited for carriers requiring connectivity across Europe, the Caucasus, and the Middle East on a single provider.

Question 7

How many Points of Presence does Sofia Connect have?

Accepted Answer

Sofia Connect operates 9 Points of Presence across three regions. In Europe: Sofia (Equinix SO1/SO2, Telepoint), Frankfurt (Equinix FR5, New Telco), Istanbul (Equinix IL2), Athens (Lamda Hellix), and London (TH North). In the Caucasus: Tbilisi (Cloud9 Data Center), Yerevan (Firebird), and Agarak (Armenia–Iran Border). In the Middle East: Dubai (Datamena DC1). This PoP footprint covers critical interconnection hubs between Western Europe, South-Eastern Europe, the Caucasus corridor, and the Middle East.

Question 8

What is NaaS and does Sofia Connect support it?

Accepted Answer

Network-as-a-Service (NaaS) is a delivery model that allows customers to configure, order, and manage network services on demand — without manual carrier intervention for each change. Sofia Connect fully supports NaaS through a self-service portal and a RESTful API. Customers can select product type, PoP, bandwidth, and contract term; receive real-time indicative pricing; and submit provisioning requests that trigger automated workflows. BGP session management, bandwidth adjustments, and service lifecycle management are all available via the portal or the API endpoint at api.sofia-connect.net.

Question 9

What SLA does Sofia Connect offer?

Accepted Answer

Sofia Connect offers a 99.99% availability SLA for IP Transit services and a 99.999% availability SLA for DWDM wavelength services. Both SLAs are backed by financial penalties: customers receive service credits when availability falls below the contracted threshold within any calendar month. The 24/7 NOC provides continuous monitoring, and protected DWDM paths include sub-50 ms automatic failover switching. SLA terms are defined per service type in the Master Service Agreement and can be customized for enterprise or carrier-grade contracts.

Question 10

How can I get a quote from Sofia Connect?

Accepted Answer

Quotes can be obtained through three channels. First, via the NaaS self-service portal, which provides real-time indicative pricing for IP Transit, Ethernet/L2VPN, DWDM wavelengths, and Dark Fiber. Second, via the website contact form at sofia-connect.net/contact, where the sales team responds within one business day. Third, by contacting the sales team directly at sales@sofia-connect.net or by phone at +35924200300. For enterprise and carrier agreements requiring custom terms, SLAs, or route engineering, direct contact is recommended.

Question 11

What is Sofia Connect's ASN?

Accepted Answer

Sofia Connect's Autonomous System Number is AS47872. It is registered with RIPE NCC, the Regional Internet Registry for Europe, the Middle East, and Central Asia. AS47872 maintains BGP sessions with 96+ peer networks at major Internet Exchange Points including BIXP (Sofia), DE-CIX (Frankfurt), Equinix Istanbul, and others. The ASN can be verified in the RIPE NCC database at ripe.net.

Question 12

Does Sofia Connect support IPv6?

Accepted Answer

Yes. Sofia Connect supports IPv6 in dual-stack mode across all services. Both IPv4 and IPv6 routing tables are advertised to IP Transit customers via BGP, and all PoP infrastructure is dual-stack enabled. Customers can request IPv6 address space allocation or bring their own Provider Independent (PI) address space and announce it via their BGP session with AS47872. IPv6 support is included at no additional cost for IP Transit customers.
