    Rob Ricci (ricci@discuss.systems)'s status on Friday, 25-Apr-2025 15:03:25 JST Rob Ricci Rob Ricci

    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 .

    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

      BlueCry isn't federated. I don't understand why anyone would use it. The PDS servers don't talk to each other. It's the same slop you'd get anywhere else.

      I host on Hetzner and it's popular because it can be very cheap. You're basically using old hardware. (One of my hosts is old server grade hardware and the other is an old gaming motherboard).

      The biggest problem with fedi is the blocklists and censorship. My domain is instantly blocked by any moron who sets up a new server and blindly imports a block list. Nostr seems to be a better solution, but its userbase has fallen heavily.

      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.

      Are you new here? Most of the block lists out there contain hundreds, if not thousands, of single user instances and dead servers. People who maintain these lists will just add anyone for the slightest reason. Your own instance silences my server and I've even contributed to the Mastodon codebase. People accused me of 'ban evading' when I set up my Pleroma server, even those I have the same username, icon and it's very clearly me.

      If you switched from mastodon.social to a place such as shitposter.world or noauthority.social, you would see an ENTIRELY different version of the fediverse.

      @djsumdog @ricci why would importing a block list block yours? only if your setup was on it tho right, not otherwise?

      it would be pretty unusual for people to go blocking whole servers they havent even heard from I would think. I likely am missing something about how it works.
