tomIs it theoretically or practically possible for a TCP connection to fail to setup over a loopback interface? Assuming the transport is perfectly ideal eg, the linux kernel loopback interface; Can you expect TCP to work 100% of the time?
jonas’there are always resource limits which can be hit, e.g. lack of available source ports
tomSay you check the return code of prosody's HTTP server for a 200OK every 10 seconds for months on end
tomOtherwise the logs don't report anything good AND the daemon quitting successfully with a regular SIGTERM
tomShould I suspect prosody's failure or check_http's failure
tomI've got plenty of headroom there jonas
jonas’tom, which daemon quit?
tomI have a screen which checks prosody's health every 10 seconds
tomAnd restarts the daemon if it doesn't work
Licaon_KterOVH on fire, everyone is up?
tomWhat kind of hosting company releases updates over some third party social media service instead of their own website
tomThat is laughable
jonas’using a third party service is exactly what you should do
jonas’and exactly what should be in your plans
jonas’when your DC is on fire, you cannot rely on your own website being available
tomSpeaking of, what kind of datacenter catches on fire
jonas’any datacenter can catch fire
tomTheir built not to though
jonas’rumors are that this was an arc fault in DC equipment. if that happens at the right amperage, you can only let it burn down
tomHalon systems and whatnot
jonas’halon systems are forbidden in the EU since the 90ies

OVH is big enough to have an HA webserver, or at least anycast

jonas’tom, they also have that: https://status.us.ovhcloud.com/
jonas’so maybe also stop assuming that twitter is their only communication channel ;)
jonas’also, if you are the CEO of a cloud company whose DC just literally went up in flames… I don’t fucking blame you for using twitter.
tomThanks for that list Licaon_Kter
mikeYeah that's about when I last recall seeing it online.
» <jonas’> also, if you are the CEO of a cloud company whose DC just literally went up in flames… I don’t fucking blame you for using twitter.
jonas’, when disasters happen on this scale there were several things and factors that were festering for a very long time that allow them to happen
jonas’tom, I don’t think that’s necessarily true.
Licaon_Ktertom: fire and twitter accounts don't mix, c'mon
jonas’but before speculating, maybe wait for a post mortem?
Licaon_KterI bet the CEO did not put the nuts and bolt of the building :)
Licaon_KterYes, hopefully they'll do a postmortem
tomMismanagement at best
jonas’also, I’d like you to be a bit more thoughtful
jonas’the engineers which are now having a real bad day might even be here if they run a private XMPP server
tomWe will see
» >The last big downtime crisis at OVH also happened at the Strasbourg campus. A power outage in 2017 brought the entire campus down. Forty minutes later, its campus in Roubaix lost connectivity due to an unrelated software bug in networking equipment.
tomThey have been having "power problems" for a very long time

Licaon_Ktermoparisthebest: the "known" but not taken down part is...odd...c'mon...
KrisI find it interesting in just how much the cloud hosting pricing race to the bottom has not only resulted in massive overprovisioning of VPS hardware, but also servers being hosted in litteral old shipping containers (and buildings that seem hardly more in substance).

moparisthebestare you saying recycling is bad ? :P
Krisdoes anyone remember that study that showed most xmpp servers are hosted on Hetzner infra? all I can find right now is a similar one on Mastodon servers: https://bitkeks.eu/blog/2020/03/underlying-problem-fediverse-decentralised-platforms.html
moparisthebestI'm not sure that's a problem though, I mean, assuming proper backups etc it should be easy to quickly fail over to anywhere else
Kristo some extend yes. but some of the privacy benefits of xmpp are lost when the data just moves from one server to the other in the same datacenter
Krisin regards to metadata
moparisthebestI'm not sure, the datacenter has more visibility, but state actors likely have less
Licaon_KterKris: so...you say I should make my own datacenter first?
Host at home? "Oh terrible"
Host at hosting? "Oh noes"
Effing move the goalpost further
Krishostng at home (depending on your ISP) is great
Krisand at least in theory it can be even greater with ip6
Krisbut what I am actually saying: some awareness of datacenter centralisation and resulting issues is probably good to have
Krispeople complan about AWS and then happily host their stuff on Hetzner because it costs 20ct less per month
moparisthebestI don't know that there's an easy solution though, generally I like a reliable provider other people are happy with, not a brand new one I have to test first
Krisyeah no easy solutions to that one

jonas’FWIW, I don’t host at hetzner because they’re cheap, but because they’re the *only* european hoster I was able to find which:
- offers proper IPv6 (= /64 or greater, *routed* to the server)
- proper virtualization (no virtuozzo or lxc, real kvm)
- isn’t super shady, i.e. offers at least GDPR-compliant contractor things (I only know the german term, "Auftragsverarbeitungsvertrag")
jonas’if you know another ISP which offers that, I would *really* like to know, because currently most of my stuff is in the same AZ (hetzner’s) and I like cross-AZ redundancy
jonas’it still needs to be affordable though, >15 Eur/month for a mail server is not something I’m going to invest.
Krisnetcup.de has the same I think, but also in germany
moparisthebestI moved to hetzner in about 2013 after using many other hosts over many years and so far they've been the best
jonas’netcup is on my do-not-use-list
jonas’I had very bad interactions with them when moving a domain from them to another registrar
moparisthebestit's always good to see other suggestions though
beni like hetzner and ovh, currently using soyoustart
Krisah, yes they are a bit possessive of their .de domains
beni ordered an ax101 from hetzner like a month ago one evening while a bit drunk
benstill trying to decide what to put on it
moparisthebestisn't soyoustart also ovh ?
Ge0rGKris: of *their* .de domains? ;)
Ge0rGwell, DNS is obviously black magic that nobody understands.
KrisYeah, DNS... but kind of understandable as labour costs for even 5 minutes of support on 20ct/month domain name reselling basically wipes out any profit for the next 10 years.
benyeah soyoustart is an ovh sub-company
Ge0rGI'm looking for somebody from omemo.im
vanitasvitaeGe0rG, their website lists firstname.lastname@example.org
Ge0rGvanitasvitae: and their 0157 lists an email address, but they have no MX.
Ge0rGvanitasvitae: I pinged the JID an hour ago
Ge0rGmaybe I just shouldn't expect express delivery.
jonas’PSA: I changed the JID of the search.jabber.network crawler. It is now email@example.com. So don’t be surprised if you see that in your logs instead of the old firstname.lastname@example.org
