Aleksi Suhonen
Aleksi Suhonen first got on the Internet in 1987. He started working with ISPs and IXPs in 1997 and founded TREX in 2002.
Aleksi started his university studies on Computer Engineering and Software Engineering at the Tampere University of Technology in 1994, but he got swept up by work the next year. He worked on network maintenance and security at the University and later at Nokia Mobile Phones. By 1997 he had moved to SciFi Communications International, which later became better known as Saunalahti and Jippii. While there he spearheaded the international network expansion of AS6667, including connecting it to half a dozen IXPs in Europe and the United States.

Running diversely connected DNS servers requires that the list of zones and zone contents are synchronized on all servers. There are many approaches to handle this challenge, and many of them use mechanisms outside DNS. Catalog Zones are a newish mechanism that aims to do it all in-band in DNS.
Geopolitical events are already shaping how operators buy, build, and run networks — including how much they can still rely on subsea cables between the Nordics and Central Europe. This panel looks at where that pressure hits Nordic and Baltic digital infrastructure hardest, how operators mitigate it, and what role Internet Exchanges play when the political map is moving. Moderated by Theo Voss, it brings together Kārlis Svilans (CERT.LV), Kamil Szczepański (Orange Polska), Aleksi Suhonen (TREX), Kaj Kjellgren (DE-CIX), and Fredrik Korsback (Meta). The conversation will stay practical: operational resilience, interconnection, and what the community should prepare for next.
