Our CEO is in Tirana attending ANIX Meeting 2026, as the event brings together a fast-growing and increasingly ambitious Albanian Internet and connectivity ecosystem.
There is strong momentum among local companies and a clear focus on closer integration with the European digital market. Expectations are high that a VIP / fast-track agreement with the EU could be achieved by the end of this year or in early 2027, marking an important milestone for the region.
We look forward to the discussions and insights over the coming days.

A solid kick-start of the year with a working event.

This January, our CEO Konstantin Ternianov attending the annual Pacific Telecommunications Council (PTC '26) Conference in Honolulu.

Fellow colleagues consistently describe PTC as one of the strongest events in our industry, and this year marks an important milestone — it will be the first time our company TBISS Ltd. participates and is represented.

See you there — hopefully in Hawaiian shirts and flip-flops ☀️

Netnod Technical Meeting 2025
What a fantastic event! The venue — Södra Teatern in Stockholm — couldn’t have been more perfect: that old, cozy atmosphere in beautiful contrast with the cutting-edge technology that brought us all together.

The agenda was perfectly balanced, with just the right mix of deep technical talks and broader industry insights — as always!

A warm thank you to the one and only Leo Bernava, who, as always, makes these events feel both professional and personal. Your energy and dedication make the difference every single time.

New 25G interconnection live in Sofia

This week we successfully set up a new 25 Gbps port with Inter.link in Sofia.

The process was not without challenges – our MikroTik gear on one side and Arista on the other refused to establish a link, even though we had optical power in both directions.

That’s where the right tools and the right people made all the difference:

Thanks to FLEXOPTIX GmbH and their multi-vendor transceivers & programmer, I could re-configure the module until it matched perfectly.

Thanks to Airbeam - Telecommunication Networks for delivering the 25G module so quickly, literally saving the day.

And a special thanks to Livio Morina for jumping in and helping to troubleshoot until the connection lit up.

Without FlexOptics flexibility and teamwork from partners, this interconnection wouldn’t have gone live so smoothly.

Another strong step forward for TBISS Ltd. in building robust connectivity across Sofia.

The event season is about to start — and we’re kicking it off with a fantastic double in Bucharest!

Our CEO Konstantin Ternianov will join the European Peering Forum 2025 (15–17 September) followed right after by RONOG 10 (18 September).

Almost a full week of face-to-face meetings, official sessions, social events, and private catch-ups with old friends and new faces in the peering community.

05/09/2025

Yesterday morning, a Google outage hit Bulgaria and the region, disrupting Search, YouTube, Gmail, and Google Cloud for many users.

At TBISS, none of our clients were affected.
Why?

Private peering with Google at multiple European cities (Sofia, Amsterdam, Frankfurt, London etc.).
30+ active routes to Google via direct peerings and upstreams.
High-capacity bandwidth channels that prevent congestion, even during outages.

Our NOC team acted instantly when some routes stayed “up” but stopped working — manually rerouting traffic around 08:00 AM.
The result: uninterrupted service for all TBISS Ltd. clients.

Full transparency:
Clients can check this themselves in the TBISS Partners Portal: partners.tbros.net
and the public can see it in our Looking Glass: lg.tbros.net

This incident is a reminder that even the biggest networks can fail — but resilience, redundancy, capacity, and transparency make all the difference.
