Re: Datacenter switches
by Philipp Tobler 27 Apr '23

27 Apr '23

Hi Matthias, at the University of Bern, we are replacing our current Enterasys/Extreme/Brocade/Ruckus gear by Extreme Network models. For core/distribution/ToR, we opted for the 7400 and 5520 series with VOSS (Fabric engine) and so far, we are quite happy with the choice. The 5520-24x could fit your requirements - 10G copper is feasible with copper plugins. (max. 50% of copper plugins supported due to heat discipation) BTW, we use a mix of „original“ and Fexoptix plugins. Hope this helps - otherwise feel free to give me a call.

Datacenter switches
by Matthias Hertzog 27 Apr '23

27 Apr '23

Dear colleagues As some of you already figured, i‘m about to dive into the ISP scene again. „What a surprise“ ;-) I‘m currently evaluating datacenter switches. Current need is at least 12 10gig SFP ports and some 10gig copper ports. What brands and models are you guys using these days? I‘ve used cisco and Foundry/Brocade in the past, but i‘m open for recommendations. Thanks & have a nice day, Matthias

Looking for a /24. (or /23 or /22)

Hi there! I’m looking for a /24 to buy. I have my own LIR and know how the transfer works. If you have something for sale, please let me know before i dive into the RIPE listing service and grow more grey hair due to non-responding people in there. Immediate and hassle-free payment guaranteed. Thanks & best wishes, Matthias

Anyone IT/Email/Marketing contact at United Nations or Geneva Forum or Objectif Sciences International
by Benoît Panizzon 11 Apr '23

11 Apr '23

Hi all Does anyone have a contact to the IT or more precisely Email / Marketing Department of the UN Geneva Forum aka Objectif Sciences International? https://www.osi-ngo.org/ They most probably have acquired an email list containing SWINOG Spamtraps and using this to advertised their science activities, getting shared Office365 IP addresses, used by the UN and other Swiss Office365 customers, blacklisted. I was in contact with the OSI Geneva Forum CEO, but he was not successful in finding anyone in charge. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Agenda
by Simon Ryf 27 Mar '23

27 Mar '23

Dear SwiNOG community, you received a few mails I intended for the swinog-core and not the public mailing list. I hope I did not disclose too much private info and on the bright side you got a sneak peak of what might come up. We will publish a preliminary agenda beginning of May. My sincere apologies. Br Simon SwiNOG

by Vincent Magnin 23 Mar '23

23 Mar '23

Dear SwiNOG community, Do you have any contact at Net4all.ch? It seems their custom "Oxito.com" (ie. DNS is no more working) is out of service. What's the status for existing clients? How to transfer existing domain out of this customer? Regards, Vincent
