Seeking for advice / Sunrise / Yallo Support issue
by Philippe Maechler 16 Oct '25

16 Oct '25

Hello List, long time lurker seldom poster here :) Sorry for posting here, but I ran out of ideas on how to solve an issue with Sunrise/Yallo. Two weeks ago, Sunrise had to move their connections in Dubendorf from Fibre-Plug 2 to 1. Just after that, I moved the CPE to Plug 1 and contacted the support because the connection was not working. Long story short: After almost two weeks, the connection is still not working. On Plug 2, I get the Fiber- or OTO Activation Screen from Swisscom and on plug 1 I don't even get an optical signal. Support promised me a temporary 5G router, a SIM card, a new Fiber Box, Calls from the technicians and so on... Nothing happened and I'm still offline If there is any Sunrise/Yallo technician out there, could you may have a look at it? If someone has an Idea on how i can escalate this, feel free to contact me Again, sorry for disturbing about a private connection and being off topic here Best regards Philippe

Business Continuity - eine kleine Geschichte...
by Matthias Leisi 03 Oct '25

03 Oct '25

Hallo allerseits, Ich möchte euch eine kleine Geschichte erzählen. Heute Nacht (vom 2. auf den 3. Oktobber 2025) gab es einen Brandalarm im „Tanklager und Unterflurbetankungsanlage Rümlang“, TAR/UBAG. Die Werksirene war im weiten Umfeld des Flughafens gut zu hören, aber offenbar ist nichts „grosses“ in Flammen aufgegangen (sonst wären die Zeitungen voll davon :) ) Aber: In gut einem Kilometer über freies Feld vom Tanklager entfernt ist das NTT Datacenter (früher eShelter), und etwa 700 Meter entfernt das Digital Realty Datacenter (früher Interxion). Zudem führt eine Gasleitung in der Nähe durch (ich gehe davon aus: mit Datenleitungen), und in der Strasse und dem Bahngleis links und rechts des Tanklagers wohl noch weitere Datenleitungen (zumindest zur Verbindung NTT - Digital Realty). Wenn im Tanklager tatsächlich ein grösserer Brand ausbricht, muss in den DCs wahrscheinlich die Frischluftzufuhr reduziert werden, damit eindringender Rauch keine grösseren Schäden verursacht - mit entsprechenden Auswirkungen auf die Kühlung. Im Worst Case müsste an beiden Standorten wegen der reduzierten Kühlung eine Menge an Infrastruktur heruntergefahren werden - und an beiden Standorten werden bekanntlich viele essenzielle Dienste betrieben. So als Denkaufgabe fürs Wochenende: Wie gut könntet ihr mit dieser Situation umgehen? Welche Zulieferer / Dienstleister sind auf eines oder beide DCs angewiesen? Wo wäre „nur“ die Redundanz gefährdet, und wo der ganze Dienst? Und wie zuverlässig sind Redundanz und Failover getestet? Viele Grüsse, Matthias

Improving our MANRS: AS-SWITCH -> AS559:AS-SWITCH
by Simon Leinen 16 Aug '25

16 Aug '25

Dear SwiNOGgers, and in particular those who peer with us (Switch), we have finally gotten around to implementing the recommendation[1] to use "hierarchical" names for our as-set in the RIPE RR/DB. So instead of "AS-SWITCH", we now use "AS559:AS-SWITCH". Please update your filter generation accordingly if you peer with us. Our PeeringDB entry[2] and AS559 policy in the RIPE DB have been updated accordingly. Thank you & best regards, -- Simon.

Looking for Swisscom endusers...
by Matthias Hertzog 04 Aug '25

04 Aug '25

Hi there! As some of you know, i’m (again) the owner of the mhs.ch <http://mhs.ch/> domain - yeee! :-) This domain was used for endusers in the @free.mhs.ch subdomain in the past. Some of these clients still have a …(a)free.mhs.ch address connected with their Swisscom account, even after the addresses were cancelled (what a shame!) by the then-owner of mhs.ch <http://mhs.ch/> years ago. I try to find these customers to help them, getting a mail-forward or simply a chance to change their Swisscom accounts to the new address. Can someone at Swisscom please get in touch with me? I don’t want the phone numbers of these customers, but i suggest that someone at Swisscom gives them a call to help solving the problem. Thanks, Matthias BTW: The Swisscom shop i’ve visited tried to help, but has no access to the database when only the e-mail address is know. M.H.

by Lüthi Marc 28 Jul '25

28 Jul '25

Dear all Could someone from Sunrise please contact me off-list? I’m having a hard time getting across support that there _is_ in fact an issue involving both IP allocation (PPP based) on a broadband service and IP Prefixes owned and routed by Sunrise. Thanks a lot Marc Lüthi EveryWare AG
