Yes, the origin server always seeds videos uploaded on it thanks to
[Webseed](http://www.bittorrent.org/beps/bep_0019.html).
-It can also be helped by other servers using [redundancy](https://docs.joinpeertube.org/#/contribute-architecture?id=redundancy-between-instances).

## What is WebSeed?
## I want to change my domain name, how can I do that?
-It's not officially supported, but you can try the `update-host` script: https://docs.joinpeertube.org/#/maintain-tools?id=update-hostjs

## Why do we have to put our Twitter username in the PeerTube configuration?
### CPU
-Except for video transcoding, a PeerTube instance is not CPU bound. Neither Nginx, PeerTube itself, PpostgreSQL nor Redis require a lot of computing power. If it were only for those, one could easily get by with just one thread/vCPU.

You will hugely benefit from at least a second thread though, because of transcoding. Transcoding _is_ very cpu intensive. It serves two purposes on a PeerTube instance: it ensures all videos can be played optimally in the web interface, and it generates different resolutions for the same video. PeerTube support for offloading transcoding to other machines is being discussed, but not yet implemented. See https://github.com/Chocobozzz/PeerTube/issues/947 .
But what if you need to serve more users? That's where PeerTube's federation feature shines. If other PeerTube instances following yours, chances are they have decided to mirror part of your instance! The feature is called "server redundancy" and caches your most popular videos to help serve additional viewers. While viewers themselves contribute a little additional bandwidth while watching the video in their browsers (mostly during surges), mirroring servers have a much greater uplink and will help your instance with sustained higher concurrent streaming.
-If all your preparations and friends' bandwidth is not enough, you might prefer serving files from a CDN ; see our [remote storage guide](https://docs.joinpeertube.org/#/admin-remote-storage).

## Can I seed videos with my classic BitTorrent client (Transmission, rTorrent...)?
