OVH: the biggest and fastest growing autonomous system
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, OVH is by far the biggest AS on the tor network, in terms of consensus weight (>12%), guard probability (>15%), middle propability (>14%) and in the top 3 by exit probability(>7%). Here are some AS stats for June 2015, that show which ASes added most bandwidth/CW to the tor network. This shows that OVH is not only the biggest AS but also the fasted growing AS: +-------------------------------------+---------+-------------------+ | as_name | new_FPs | added_CW_fraction | +-------------------------------------+---------+-------------------+ | OVH SAS | 98 | 2.129 | | Digital Ocean, Inc. | 44 | 0.936 | | Internet Assigned Numbers Authority | 23 | 0.911 | | ONLINE S.A.S. | 23 | 0.594 | | SOFTplus Entwicklungen GmbH | 4 | 0.512 | | STRATO AG | 8 | 0.274 | | Contabo GmbH | 9 | 0.200 | | LDeX Connect LTD | 5 | 0.200 | | myLoc managed IT AG | 7 | 0.178 | | Core-Backbone GmbH | 2 | 0.160 | | PlusServer AG | 9 | 0.141 | | PCextreme B.V. | 1 | 0.119 | | Hetzner Online AG | 30 | 0.113 | | ISPpro Internet KG | 3 | 0.113 | | United Gameserver GmbH | 4 | 0.107 | | BlazingFast LLC | 12 | 0.101 | | WorldStream | 19 | 0.092 | +-------------------------------------+---------+-------------------+ new_FPs: number of relays (identified by fingerprint) that were first seen in June 2015 and were still running at some point during the last 7 days added_CW_fraction aggregated CW fraction of relays identified in the new_FPs column If you want to help stop this trend, and make the tor network more diverse, choose non-top 10 ASes when adding relays (10 is an arbitrary number).

Your table list “Internet Assigned Numbers Authority”. Where does that come frome? [...] I know that ICANN has an AS, but I haven't been able to find one for IANA.
I should have included information about what data this is based on. I used onionoo.torproject.org data from 2015-07-04 16:00 (relays_published timestamp). Regarding the AS named "Internet Assigned Numbers Authority", this is actually not a real AS, but the 32bit transition AS23456 specified in https://tools.ietf.org/html/rfc6793 If you look at the same IPs a ~week later (2015-07-10 17:00) all of the - still running - former AS23456 IPs "became" part of one of several Digital Ocean ASes (AS202109, AS201229, AS200130) - so we can assume that onionoo.tpo updated its IP-AS database somewhere between 2015-07-04 and 2015-07-10. I guess onionoo.tpo uses maxmind as data source. If we look at the list of added relays (June 2015) again based on onionoo.tpo data from 2015-07-10 17:00 - includes relays still running at some point within the week before that date, IANA is no longer present: +-----------------------------+---------+-----------------+ | as_name | new_FPs | new_CW_fraction | +-----------------------------+---------+-----------------+ | OVH SAS | 70 | 2.624 | | Digital Ocean, Inc. | 56 | 0.977 | | ONLINE S.A.S. | 21 | 0.838 | | Hetzner Online AG | 18 | 0.554 | | SOFTplus Entwicklungen GmbH | 4 | 0.422 | | Contabo GmbH | 10 | 0.307 | | STRATO AG | 8 | 0.235 | | United Gameserver GmbH | 4 | 0.129 | | myLoc managed IT AG | 6 | 0.128 | | GTT a.s. | 2 | 0.125 | | BlazingFast LLC | 8 | 0.119 | | ISPpro Internet KG | 3 | 0.116 | | Init7 (Switzerland) Ltd. | 4 | 0.111 | | WorldStream | 10 | 0.109 | +-----------------------------+---------+-----------------+ Note: AS names are not unique identifiers like AS numbers.
