sendinblue / newsletter sender whitelisting?
by Michael Koloff 01 Jul '21

01 Jul '21

Hello Together Question for mail infrastructure operators: In the last weeks we had requests from customers, whose "newsletter" via sendinblue could not be delivered to us. In the logs I see at the given time, that the IP of sendinblue was on the blacklist of spamcop.net. That is, the mails were rejected by us. The customer now says the mails go through everywhere else (I'm looking at you bluewin.ch), just not with you. sendinblue suggests to whitelist their IPs (> 100'000 ip addresses) (https://help.sendinblue.com/hc/de/articles/208848409-SendinBlue-IP-Bereiche) Of course I would like to avoid this. Question: How do other providers deal with such senders? Let everything from sendinblue through for the sake of the customers? Thanks for your answers. -- Michael Koloff sasag Kabelkommunikation AG

MELANI BGP Blackhole Service
by Fredy Künzler 29 Jun '21

29 Jun '21

A customer (!) pointed us to the MELANI BGP Blackhole Service which has been around for almost two years, apparently. For technical details see the attached file. Are we the only ones not aware of it? I don't recall an official announcement by the MELANI team in this list or elsewhere in the community, and as far as I know it hasn't been discussed yet within SwiNOG. While the technical implementation seems to be rather simple - an eBGP multihop session to the IP address mentioned (hosted by nine.ch), a number of legal, operational and political questions are remaining: - no IPv6 implementation, no backup (2nd) host - how is the list of IP addresses maintained? Is there a regular check and removal procedure of no-longer-botnet-addresses? - is there any guarantee that the infrastructure will never be abused for (state) censorship? - how to implement it only for end users which do want the service while not distributing the black holes in the whole backbone - and, last but not least, why MELANI team or the so called "Outreach Team vom Bund" (Quote customers email) never told the SwiNOG community about the idea? Instead, they are suggesting strange things: "Gemäss outreach, ist das bei Init7 nicht möglich da dieses gegen eure Policy verstosst?" I suppose MELANI and the "Outreach Team vom Bund" should give some explanations. They do know where to find the SwiNOG community, and their style of (non-)communication is not acceptable. -- Fredy Künzler Init7 (Switzerland) Ltd.

more S3
by Eliot Lear 28 Jun '21

28 Jun '21

Colleagues, Sorry for the terse note earlier (I hit the wrong key). In any case, I was seeing latency of anywhere from 89-300ms earlier from two vantage points- Cablecom, where it is still a bit of an issue, and Datasource, where it is now clearing. Eliot

SSL Certs question
by Andreas Fink 20 May '21

20 May '21

Hello all, I need to get some SSL certificates for some african country operations and i can unfortunately not use letsencrypt for this. I was trying to get a certificate from Swissign for this but for some reason they refuse issuing certificates to domains for Guinea and Guinea Bissau because these countries are on their embargo TLD list. It is known that some individuals from these countries are on a UN embargo list, but thats also true for some people from Germany or Switzerland or USA. And these countries are not blocked. In other words, I need another certificate provider, preferrably not under US control (so not Comodo, Digicert, Thawte, Symantec, Verisign etc), who can issue multidomain certificates for .gw, .com.gn, .sl, .io, .com domains. Anyone have a good hint?

strange download/upload speeds with ADSL : UL faster than DL
by Charles Bueche 07 May '21

07 May '21

Hello everyone, first I hope this is not too off-topic. I'm asking here because this whole layer-1 world is quite foreign to me, despite having studied electronics 30 years ago, and I have noticed some people here really know what this is all about :-) In short : my house is cabled over ADSL (aerial line). The upgrade to G.Fast is planned for July, most probably still over the aerial line. I had serious connectivity issues when it was raining, and had Swisscom/Cablex replace my aerial line (aluminium+paper, 40+ years old) by a new shiny big shielded cable, along with all the internal cabling well-done, direct cabling for the U72, new sockets and cables, etc. The current "should" speed numbers from Swisscom check-tool are : Download : 50 Mbit/s au max. au lieu de 200 Mbit/s Upload : 18 Mbit/s au max. au lieu de 100 Mbit/s However, when testing my speed, I consistently find DL at 18-19 Mbis/s and UL at 25-29 Mb/s, with a latency at about 12ms. I have done the tests with my "real" environment (ADSL bridged-modem, Unifi USG, etc) and as well with the modem in "home-office" mode, eg ADSL-router doing the PPPoE by itself, the numbers are very similar. I used several test-sites and clients, wired and not. Almost always the same numbers. Now I'm not sure why my UL is faster than my DL. After helping to have my line replaced, my provider (Solnet) said all is ok and the problem is elsewhere... but where ? Why is UL faster than DL, and why not the 50mb/s they say ? And will it really be better with g.fast, or should I go to UPC, which I'd rather not have to.... Hints welcome :-) Charles -- Charles Bueche <cblists(a)bueche.ch>
