Chatmail relays are a really great thing which help to increase resiliency of communication. And they work really really well โค But to get **real** resilience it would make sense to help users to choose relays which are **not** hosted in the same datacenter. Some of you might have noticed that hosters and services like VSys / njal.la / [nerdvpn.de](http://nerdvpn.de) and others have been hit hard by the terroristic attack from Russia against two Kyiv datacenters on 23th of September. If you want to know more, I added two links here. \[1\]\[2\] Because of this my idea was to **add four more details** to the [official relay list](https://chatmail.at/relays) which are way more relevant than the current text telling which country the chatmail operator wants to address with the CM relay: - Datacenter - Country this datacenter resides - Availability (maybe use a tool like Uptime Kuma for that) - IPv6 available yes/no As all those things can change at any time I would recommend to make the list **dynamic** so it updates on a hourly / daily / weekly basis. Iโ€™m thinking about the list looking like this as an example (created 2026-09-26 20:15): | Relay | Availability | AS (Datacenter) | Country | Description | IPv6 | | --- | --- | --- | --- | --- | --- | | [nine.testrun.org](http://nine.testrun.org) | 99,99% | `24940 (HETZNER-AS): 77.42.49.41` `24940 (HETZNER-AS): 2a01:4f9:fff1:59::1` | DE ๐Ÿ‡ฉ๐Ÿ‡ช | is the default onboarding relay for many chatmail apps | โœ… | | mehl.cloud | 99,99% | `24940 (HETZNER-AS): 95.217.223.172` `24940 (HETZNER-AS): 2a01:4f9:c012:a1bc::1` | DE ๐Ÿ‡ฉ๐Ÿ‡ช | is geared towards German speaking users | โœ… | | mailchat.pl | 99,99% | `24940 (HETZNER-AS): 46.62.144.137` `24940 (HETZNER-AS): 2a01:4f9:c012:e6c3::1` | DE ๐Ÿ‡ฉ๐Ÿ‡ช | is geared towards Polish speaking users | โœ… | | chatmail.woodpeckersnest.space | 99,99% | `8560 (IONOS-AS): 85.215.162.146` | DE ๐Ÿ‡ฉ๐Ÿ‡ช | are focused on Italian speaking users | โŒ | | chatmail.culturanerd.it | 99,99% | `8560 (IONOS-AS): 82.165.94.165` `8560 (IONOS-AS): 2a02:2479:60:c900::1` | DE ๐Ÿ‡ฉ๐Ÿ‡ช ??? | are focused on Italian speaking users | โœ… | | [chat.adminforge.de](http://chat.adminforge.de) | 99,99% | `24940 (HETZNER-AS): 94.130.17.142` `24940 (HETZNER-AS): 2a01:4f8:10b:1666::142` | DE ๐Ÿ‡ฉ๐Ÿ‡ช | is hosted in Falkenstein, Germany and is geared towards German speaking users | โœ… | | chika.aangat.lahat.computer | 99,99% | `47066 (PRGMR, US): 71.19.150.113` `47066 (PRGMR, US): 2605:2700:0:5:a800:ff:fed7:6162` | US ๐Ÿ‡บ๐Ÿ‡ธ | is hosted in Santa Clara, California US | โœ… | | tarpit.fun | 99,99% | `197540 (NETCUP-AS): 152.53.86.246` `197540 (NETCUP-AS): 2a0a:4cc0:c0:229c:9409:d6ff:fe22:4270` | DE ๐Ÿ‡ฉ๐Ÿ‡ช | is hosted in Nuremberg, Germany | โœ… | | d.gaufr.es | 99,99% | `16276 (OVH, FR): 51.77.140.91` `16276 (OVH, FR): 2001:41d0:404:200::787` | FR ๐Ÿ‡ซ๐Ÿ‡ท | is hosted in Roubaix, France | โœ… | | chtml.ca | 99,99% | `16276 (OVH, FR): 51.222.156.177` `16276 (OVH, FR): 2607:5300:205:200::21eb` | FR ๐Ÿ‡ซ๐Ÿ‡ท ??? | is hosted in Quebec, Canada | โœ… | | e2ee.wang | 99,99% | `20473 (AS-VULTR, US): 139.84.233.161` `20473 (AS-VULTR, US): 2a05:f480:3000:26a8:5400:5ff:fe6c:9f19` | US ๐Ÿ‡บ๐Ÿ‡ธ ??? | is hosted in Johannesburg, South Africa | โœ… | | [chat.privittytech.com](http://chat.privittytech.com) | 99,99% | `16509 (AMAZON-02, US): 35.154.144.0` | US ๐Ÿ‡บ๐Ÿ‡ธ ??? | is hosted in Bangalore, India | โŒ | | e2ee.im | 99,99% | `215659 (MOEMOEKYUN, RO): 93.113.25.61` | RO ๐Ÿ‡ท๐Ÿ‡ด | is hosted in Orastie, Romania | โŒ | | chatmail.email | 99,99% | `16276 (OVH, FR): 57.128.220.120` `16276 (OVH, FR): 2001:41d0:601:1100::2674` | FR ๐Ÿ‡ซ๐Ÿ‡ท ??? | is hosted in Warsaw, Poland | โœ… | | chat.in-the.eu | 99,99% | `24940 (HETZNER-AS): 78.46.190.129` `24940 (HETZNER-AS): 2a01:4f8:1c17:7b06::1` | DE ๐Ÿ‡ฉ๐Ÿ‡ช | is hosted in Falkenstein, Germany | โœ… | | chat.nuvon.app | 99,99% | `24971 (MASTER-AS): 178.238.38.165` | CZ ๐Ÿ‡จ๐Ÿ‡ฟ | is hosted in Prague, Czechia | โŒ | | [nibblehole.com](http://nibblehole.com) | 99,99% | `51395 (AS-SOFTPLUS): 94.247.42.209` `51395 (AS-SOFTPLUS): 2a0b:7140:4:1:5054:ff:fe4f:df37` | CH ๐Ÿ‡จ๐Ÿ‡ญ | is hosted in Zug, Switzerland | โœ… | | [chat.zashm.org](http://chat.zashm.org) | 99,99% | `49824 (ACTPA-AS): 91.245.76.39` | UA ๐Ÿ‡บ๐Ÿ‡ฆ | is hosted in Lviv, Ukraine | โŒ | | [chat.sus.fr](http://chat.sus.fr) | 99,99% | `60068 (CDN77 _, GB): 89.187.165.194` `200325 (BUNNYCDN, SI): 2400:52e0:1e09::889:1` | GB ๐Ÿ‡ฌ๐Ÿ‡ง / SI ๐Ÿ‡ธ๐Ÿ‡ฎ | is hosted in Iceland, Japan, Kenya, and South Africa | โœ… | | delta.thelab.uno | 99,99% | `16276 (OVH, FR): 146.59.228.39` `16276 (OVH, FR): 2001:41d0:305:2100::debe` | FR ๐Ÿ‡ซ๐Ÿ‡ท | is hosted in Gravelines, France | โœ… | | chat.vim.wtf | 99,99% | `24940 (HETZNER-AS): 116.203.206.170` `24940 (HETZNER-AS): 2a01:4f8:1c19:1c94::1` | DE ๐Ÿ‡ฉ๐Ÿ‡ช | is hosted in Frankfurt, Germany | โœ… | | uninterest.ing | 99,99% | `36352 (AS-COLOCROSSING, US): 172.245.70.237` | US ๐Ÿ‡บ๐Ÿ‡ธ | is hosted in Elk Grove Village, Illinois US | โŒ | | [sweetfern.net](http://sweetfern.net) | 99,99% | `16276 (OVH, FR): 51.81.78.167` `16276 (OVH, FR): 2604:2dc0:401:800:0:ffff:3351:4ea7` | FR ๐Ÿ‡ซ๐Ÿ‡ท ??? | is hosted in Ashburn, Virginia US | โœ… | | [delta.disobey.net](http://delta.disobey.net) | 99,99% | `200651 (FLOKINET, IS): 185.246.190.71` `200651 (FLOKINET, IS): 2a06:1700:4:357::7b57:2a6a` | IS ๐Ÿ‡ฎ๐Ÿ‡ธ | is hosted in Roon, Netherlands | โœ… | > Disclaimer: Table was 100% crafted by a human hand, no โ€œAIโ€ involved for absolutely nothing. #fckaislop Maybe we could also offer to group / sort relays by availability, datacenter or country then. Regarding the availability topic I could imagine (or also host this on a volunteer basis if it helps the project) to have a page [like this](https://status.sweetgood.de/status/securechat) for every publicly communicated relay which ping-checks all relevant chatmail services. The table also showed me that [chat.sus.fr](http://chat.sus.fr) for example claims being hosted in different countries. But as there seems to be a CDN involved (which from my perspective is a single-point-of-failure) I donโ€™t know yet how to deal with such a situation in practice. Because if the CDN is down the server is down as well. I think a CDN like Cloudflare ditches the whole idea of resilience somehow ๐Ÿค” Regarding the work: If nobody wants to pick up the task to create a script which automatically generates an output like the table above I would provide my help here and offer to do it. But I wanted to talk to you guys first before starting (I mean I already started by creating this table as a PoC) ๐Ÿ˜‰ Looking forward to your thoughts on that ๐Ÿ™ * * * 1.

Iโ€™m not someone who can promise that this will end up on [https://chatmail.at](https://chatmail.at), even as a link to another website, but I think itโ€™s cool regardless. So if I were you, Iโ€™d do it (as long as Iโ€™m motivated) regardless. ---

What exactly are you talking about? The script which generates a table like above or the Uptime Kuma thing? ๐Ÿ˜‰ ---

It goes for both I guess.
