Haiku nightlies site moved!
Effective immediately, the Haiku Nightlies page has moved from http://haiku-files.org/ to http://download.haiku-os.org/.
It was agreed that the nightly downloads location should be a bit more centralized around the main website domain. Oliver and Niels got busy setting up a new buildbot instance and the new nightly pages, and finished it sometime last week.
The "automatic update" repositories have also moved, they can now be (temporarily) found at http://download.haiku-os.org/haiku-repositories/. Sometime before the next release, these will likely be migrated to http://packages.haiku-os.org/, but this is lower priority for now.

Re: Haiku nightlies site moved!
I suggest re-directing http://www.haiku-files.org/haiku/development/ to http://download.haiku-os.org/nightly-images/x86_gcc2_hybrid/
Re: Haiku nightlies site moved!
Maybe a link on that page with a large red warning...
Otherwise, I don't think the new location contain all the historical images, so haiku-files.org is the only place to get them still.
