bluewin mail servers "load balancers" don't like AAAA -> breaks email
by Jeroen Massar 02 Nov '07

02 Nov '07

As somebody else mentioned today there seems to be something fishy with the bluewin mailservers, I guess the culprit is the "Load balances" which seem to act as NS's. But as these are really nice Load Balancers are future proof, the real hurdle they are hitting is quite simple: that bloody IPv6... Lets dig the loadbalancers [1] for the answer: 8<--------------------------------------------------------------------- $ dig @ns.bwlbmsg1zhh.bluewin.ch. mxbw.bluewin.ch. aaaa ; <<>> DiG 9.4.1-P1 <<>> @ns.bwlbmsg1zhh.bluewin.ch. mxbw.bluewin.ch. aaaa ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 22394 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;mxbw.bluewin.ch. IN AAAA ;; Query time: 16 msec ;; SERVER: 195.186.19.8#53(195.186.19.8) ;; WHEN: Wed Oct 31 19:12:42 2007 ;; MSG SIZE rcvd: 33 --------------------------------------------------------------------->8 And tada, my sweet postfix/bind/powerdns combo will give up on it as there is clearly no answer to be gotten for that hostlabel. As such I would *love* to mail postmaster(a)bluewin.ch (assuming that somebody is at home there), but without taking out AAAA requesting out the whole chain of software I really can't mail them :( Not falling over the folks from Bluewin, but it is the only way to contact them AND to show how things can break in mysterious ways :( The BBC had a similar problem a few years back. I do hope that you folks can fix this up, I noticed this actually because a @bluewin.ch user couldn't signup to SixXS as she was getting rejected. Hmmmm, now that we are trying to query those boxes some more I can't get this answer out of this setup.... Please folks @ Bluewin, check this out and fix it ;) Greets, Jeroen -- [1] dig +trace mxbw.bluewin.ch (sometimes apparently) reveals: <snip> bluewin.ch. 43200 IN NS dns2.bluewin.ch. bluewin.ch. 43200 IN NS dns4.bluewin.ch. bluewin.ch. 43200 IN NS dns1.bluewin.ch. bluewin.ch. 43200 IN NS dns3.bluewin.ch. ;; Received 173 bytes from 2001:dc0:1:0:4777::140#53(sec3.apnic.net) in 482 ms mxbw.bluewin.ch. 86400 IN NS ns.bwlbmsg1zhh.bluewin.ch. mxbw.bluewin.ch. 86400 IN NS ns.bwlbmsg1zhb.bluewin.ch. ;; Received 123 bytes from 195.186.1.111#53(dns2.bluewin.ch) in 16 ms

Why is dedicated hosting so incredibly expensive in Switzerland?
by Per Jessen 29 Oct '07

29 Oct '07

This is probably somewhat off-topic, but some of you guys might have a hint for me. I've been researching the various offers of dedicated hosting in Switzerland, mostly looking at providers listed on providerliste.ch. Everything I have come across is not only 4-5 times the price of what we're renting right now (at Hetzner in Germany), it is also technically inferior. At Hetzner, the entry level DS3000 is a dual-core 64Bit AMD, 2Gb RAM and 2x400Gb disk. Plus 1Tb transfer-volume/month. This is available at EUR49/month. To get anything remotely similar in Switzerland I have to pay SFr300 or more per month. Given that we would need 4 or 5 such servers, colocation very quickly becomes interesting instead. Have I missed any really good dedicated server offerings? Any colocation places in or around Zurich you would recommend? /Per Jessen, Herrliberg
