@Eq @haitch owns the domain and offered burst related projects free vm, thats why a lot of pages running this domain.
And yes burst is community project, the 'team' is all who participate ... everyone is free to register e.g. burst.net and start a website about burst :-) @daWallet did that with web.burst-team.us / burst-team.us.
Sounds good, thank you that answers my question perfectly :D
Thankful to be a part of such an awesome community~!
