Per the INX-ZA management committee Terms of Reference, we will hold elections to elect new members to the INX management committee.  This election will be in the form of an online-only election;  and the results are expected to be announced during the INX-ZA August user meeting  (31 August).  This year, the INX user meeting will be held in conjunction with SAFNOG, and aspirants to the INXCOM are invited to speak for 3min on why they should be elected to the INXCOM during this time.

As a reminder, the INX Committee is open to anyone from the community, and is not limited to geography, nor exclusively peering participants.  The term period will be 2022-2024.

Only networks that peer at an INX-ZA managed IX may vote, and voting is restricted to one vote per organisation (ASN).  The voting period will be from 24 August 2022 06h00 UTC until 31 August 2022 13h00 UTC*  (15h00 local time)   (time dependent on whether the SAFNOG conference runs to schedule, and to ensure that the candidates have had a chance to speak).

This list is ascending alphabetically (sorted by first name).

Riaan has more than 16 years' experience working in the industry with extensive experience on Service Provider Backbone networks.  Riaan is currently forming part of the team responsible for the network design of Metrofibre Networx (core, aggregation and access).  Before that Riaan has been at Internet Solutions in various positions with the last one the lead engineer of the team responsible for the last mile access network (consisting of more than 300 access sites).

Riaan is a big supporter of peering and the peering ecosystem and has first-hand experience its benefits of keeping the traffic local and improving overall client experience, and leveraging from the inherent redundancy that peering is bringing by rerouting around problems and even at a stage assisted another operator with international capacity when all of theirs dropped… all of this over the peering fabric! 

Riaan’s vision is that by being part of the INX committee, his contributions can help in the efforts to make the ZA peering ecosystem better for the community.

William Stucke

William was educated in 17 places in 3 continents, eventually getting some weird non-specific Honours Engineering degree in London.

That's just as well, because he was a Construction, Project, Electrical, Mechanical, Systems and Control & Instrumentation Engineer and that's just in the Mining Industry.

After that, he wandered back to the Telecoms Industry and became a bit of a pain about telecoms liberalisation in Africa. Along the way, he co-founded ISOC-ZA, AfrISPA and NameSpace, and led all of them at some stage. He also made noises at ISPA, who were so glad he left that they gave him an award.

He programmed his first huge mainframe (with 36 K of hand-built Ferrite Core Memory) in 1972, built the first fibre optic network in an underground mine in 1988, started his first ISP in 1996 and did a bunch of clever stuff no one else had thought of, with lots of help from his partners, until they bailed. For his sins, he ended up being an ICASA Councillor and is now a Consultant, flogging his enormous skills (and tiny ego) on the open market.

Una Karlsen

Over a 20-year IT career, Una has worked for several small ISPs, building
and managing Network, VOIP and Billing infrastructure, starting in 2000 and
ending with a large Cloud provider in 2019. In between, she has done

support. Currently unemployed after a long bout with chronic illness, Una

has always been part of her DNA. Be it through local user groups or
training staff. A vocal advocate for IPv6 adoption since 2000, Una believes
in building things right and building them to last. This also means
building them to be fault tolerant, and where possible self healing.

Una believes in transparent governance and thinking global while acting
local. In practice this means working on solutions that fit local
situations best, learning from the experiences of others from abroad and
sharing her learnings so that results can be replicated elsewhere.
