With bluesky (mostly) going down for a few hours today, I got to wondering about how decentralized the fediverse really is in terms of where its servers are hosted. I grabbed a server list from fedidb, with network information coming from ipinfo.io .

[EDIT: I did a better analysis on a dataset of 10x as many servers, see discuss.systems/@ricci/1144003… ]

These stats are by the number of *servers* not the number of *users* (maybe I'll run those stats later).

fedidb currently tracks 2,650 servers of various types (Mastodon, pixelfed, lemmy, misskey, peertube, etc)

The fediverse is most vulnerable to disruptions at CloudFlare: 24% of Fediverse servers are behind it. Also note that this means that I don't have real data on where this 24% are located or hosted, since CloudFlare obscures this by design.

Beyond CloudFlare, the fediverse is not too concentrated on any one network. The most popular host, Hertzner, only hosts 14% of fediverse servers, and it falls off fast from there.

Here are the top networks where fediverse servers are hosted:

504 Cloudflare, Inc.
356 Hetzner Online GmbH
130 DigitalOcean, LLC
114 OVH SAS
56 netcup GmbH
55 Amazon.com, Inc.
55 Akamai Connected Cloud
36 Contabo GmbH
33 SAKURA Internet Inc.
32 The Constant Company, LLC
31 Xserver Inc.
28 SCALEWAY S.A.S.
24 Google LLC
23 Oracle Corporation
16 GMO Internet Group, Inc.
14 IONOS SE
14 FranTech Solutions
11 Hostinger International Limited
10 Nubes, LLC

Half of fediverse servers are on networks that host 50 or fewer servers - that's pretty good for resiliency.

There is even more diversity when it comes to BGP prefixes, which is good for resiliency: for example, the cloud providers that have multiple availability zones will generally have them on different prefixes, so this gets closer to giving us a picture of the specific bits of infrastructure the fediverse relies on.

The top BGP prefixes:

55 104.21.48.0/20
50 104.21.16.0/20
48 104.21.64.0/20
41 104.21.32.0/20
41 104.21.0.0/20
38 104.21.80.0/20
32 172.67.128.0/20
31 172.67.144.0/20
28 172.67.208.0/20
28 162.43.0.0/17
27 104.26.0.0/20
26 172.67.192.0/20
26 172.67.176.0/20
23 172.67.160.0/20
19 116.203.0.0/16
17 172.67.64.0/20
17 159.69.0.0/16
16 65.109.0.0/16
14 88.99.0.0/16
14 49.13.0.0/16
13 78.46.0.0/15
13 167.235.0.0/16
13 138.201.0.0/16
11 95.217.0.0/16
11 95.216.0.0/16
11 49.12.0.0/16
11 135.181.0.0/16
10 37.27.0.0/16
10 157.90.0.0/16

75% of fediverse servers are behind BGP prefixes that host 10 or fewer servers, meaning that the fediverse is *very* resilient to large network outages.

Top countries where fediverse servers are hosted:

871 United States
439 Germany
156 France
148 Japan
75 Finland
57 Canada
49 Netherlands
38 United Kingdom
26 Switzerland
26 South Korea
21 Spain
19 Sweden
18 Austria
17 Australia
15 Russia
12 Czech Republic
10 Singapore
10 Italy

One thing that's interesting to me in this data is that there is actually *much* more consolidation on a few cloud providers in Europe than there is in the US. This is actually somewhat concerning. 81% of fediverse servers in Germany are at Hetzner, 73% of the servers in France are on OVH. By comparison, the most popular American provider, Digital Ocean, hosts only 14% of servers in the US. I don't know how representative this is of cloud usage overall (eg. Digital Ocean is definitely not the top cloud in the US) but it does certainly suggest much more centralization in Europe as compared to the US.

Atlanta Radio Veteran ''Cadillac Jack'' Choate Dies at 51 news.radio-online.com/cgi-bin/…

Hey pals: Someone I like made a tool that extracts still images from youtube tutorials so we can follow them step by step with screenshots as God intended instead of having to constantly be pausing and seeking back and forth. I have LOST this precious resource.

Was it you? Will you give me the link? I will bookmark it this time.

UPDATE: FOUND. It is github.com/obra/Youtube2Webpag… by @jesse and it deserves a genius grant if we're honest

Please help the autism community of the United States be protected!
As some might know, RFK is planning to create a registry for those who are autistic. this is a violation of basic human rights, and can lead to things like nonconsensual and painful therapies, force sterilization and eugenic cleansing.
Please help the American Autistic Community, and those who support said community, raise our voices in saying no. Sign the petition, if you can.

As a reminder to my academic friends. If you are doing research that involves modifying a compiler - perhaps to add a security mitigation or to test an optimization or some other interesting behavior - and you want to run a real world benchmark or test suite: we can help you run it on Firefox.

We can get you set up with our CI so it's easy and efficient to iterate on your patches and run it through the whole gamut.

If you want a compelling story in your paper, showing results on what is probably the second most complicated piece of software in use ought to do it.

They also recently started selling these: Handmade Foldable Tote Bag & Carrying Pouch. There are multiple patterns, I've personally been rocking the Grogu/Baby Yoda one, but there are mushrooms, cats in multiple colors, and more. Impossibly cute, and it folds up into this tiny little pouch with a button for securing. All sowed by hand, directly outside my bedroom door. etsy.com/listing/4295110843/ha…

This is just your periodic reminder that if you need a new place to hang something, this instance has never closed signups in its existence and never plans to. You'll never need a million character limit, but we have one. We run Glitch-soc, and I've been known to submit or bump bug reports/feature requests for both Glitch and the stock Mastodon versions. Signups are restricted and you absolutely do require a reason, so this instance will never be nicoled. Oh, and I give 0 fucks as long as you follow the rules, which are common sense (I hope). Want a place to hide? Well, maybe Mastodon isn't that place - but if you want a place to hang out and cause trouble, we're open. allovertheplace.ca

if I where to setup a new @matrix@mastodon.matrix.org which server software is nicer to work with?

Synapse Or Conduit?

synapse seemingly has the pro in terms of support for tools such as synapse admin: github.com/Awesome-Technologie…
and the ability to use oauth and handle user management using solutions such as authentik.

while conduit seems to be more resource efficient and better in terms of speed?
