Mastodon

Mastodon is a federated social network which is comparable in functionality to Twitter and part of the Fediverse. Due to the federation, instances are constantly joining the network or disappearing.
As of January 2019, it is not possible to properly migrate an account from one instance to another.
Since May 2019, ArchiveTeam has not archived Mastodon or any other Fediverse instances; see the Fediverse page for details.
== Archival ==
Instances can be archived reasonably well by starting a recursive crawl from the "about" page, which contains a link to the admin profile. This may not cover the entire instance though. A more complete coverage requires first crawling the API to retrieve a full list of accounts on the instance, then starting a recursive crawl from those. The API as well as the ActivityPub endpoints also offer other ways to obtain a dump of the status data, e.g. by iterating over the public timeline or over the accounts' outboxes; this does not produce (easily) browsable archives but can be accessed much better programmatically.
A patchset for a CLI Mastodon viewer can output URLs for archiving, including JavaScript based pages, the API requests they make and RSS URLs as well as outlink URLs, but it is not production ready yet and only intended for targeted archiving.
Mastodon has a built-in feature allowing for automatic post deletion, instancewide or at the behest of individual users .
== Lists of instances ==
* – As of 2019-01-15, this lists 6066 instances, a bit over 4100 of which are marked as down.
** The full list as JSON is available .
* – Not only Mastodon but the entire Fediverse. Opt-in and therefore incomplete. As of 2019-01-28, 4298 nodes (instances) are listed in total, 2748 of them running Mastodon.
* – Automated discovery through each instance's peers. Covers also GNU social, Pleroma, and Misskey.

=== Outdated instances ===
Instances that are running old versions of Mastodon are likely to not be properly maintained anymore and may be at risk of disappearing. They are tracked at:
