Swisscom (Emergency) Phone Outage Post-Mortem
by Tobias Brunner 12 Jul '21

12 Jul '21

Hi all, Does anyone see a chance to get hands on the post-mortem they (hopefully) write about the phone outage from last week? I'm very interested in technical details, as I always feel that from such stories we can all learn and improve. Cheers, Tobias

Geldspielgesetz: 404 COMLOT renamed to GESPA? (or did they get hacked!?)
by Jeroen Massar 07 Jul '21

07 Jul '21

Hi Folks, Is there an official announcement that I missed? Seems that blocklist.gespa.ch is the new place, and that all of comlot.ch now points to gespa.ch, but filenames have been renamed too. (see previous brokeness email in the mailarchive for old details). Considering neither is under admin.ch, cannot really say it is an official website either. Anybody got an official update about this, or did they just break the system again? Cannot find any duckduckgoogle references either. Why did Swiss Voters vote for this broken system if it is not working anyway? (it is not, because otherwise it is a perfect list to find your casinos that are 'illegal' or something).... All those poor* casino users that now have access to a bunch of unlicensed casinos... what a sad day again.

I also gotta love the generic wildcard Let's Encrypt cert, though comlot.ch did that too https://crt.sh/?q=gespa.ch https://crt.sh/?q=comlot.ch Looks like a rather generic hoster. Maybe the whole domain got hacked?

Cloudflare DMCA Takedown requests - but content not present under mentioned IP
by Benoit Panizzon 06 Jul '21

06 Jul '21

Dear List I am a bit puzzled by repeated Cloudflare Takedown Requests regarding the domain: lord-film.cash we are getting. lord-film.cash has address 172.67.181.230 lord-film.cash has address 104.21.32.5 lord-film.cash has IPv6 address 2606:4700:3035::6815:2005 lord-film.cash has IPv6 address 2606:4700:3032::ac43:b5e6 According to Cloudflare, the content is hosted at an IP address under our control, on a Webserver on Port 80. I told them some time ago, there is no Webserver running under the IP address they mention. They replied, they could verify the IP with: curl -v -H "Host: lord-film.cash" [IPADDRESS]/ Still, every time I try, I don't get a connection. No wonder, that is a NAT router with Firewall. So I wonder, if either the user of that IP Address has cleverly set up a firewall which blocks all requests not via Cloudflare proxies, or if this domain uses some kind of P2P Protocol and the IP of that user is just one of 'many' which is only reachable, when some P2P tool is running and opening a UPNP Port. When I try to access the site itself: http://lord-film.cash/ I get 'access denied' from Cloudflare. Do others get similar takedown notices? Maybe even for that same domain?

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

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
