yes, sadly both maemo.org and garage.maemo.org are down and most likely will remain like that for now. As it has been explained to me these websites depend on older cms technology that is unlikely to get upgraded and is also probably not worth the time and effort to change that.

The website is fully archived in archive.org for anyone to use.

We have to be thankful to the folks that have kept the project websites, repositories and forums online and operation all these years. That alone is one of the greatest contributions of all.
