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.
