The current issue with tablets-dev (which I foolishly... after migration ...thought was resolved) is an old issue with Nokia...that started pre-migration.

Currently...
Unless it is Nokia providing the download of ANYTHING from tablets-dev. (esp for the n770/n800/n810/n900)....such as the flashers and the firmware... at this point WHOEVER hosts a new download link would be under threat of being pulled or shut down ....
...and the possibility of legal action can't be ruled out...
It is (now) illegal until some issues are sorted out with Nokia.

As I fathom it...There are 3 options here.

#1- Openly (and I personally think... very very foolishly) defy legal trademark and copyright putting your own, others...and possibly the community (as a whole... if there is implication) at risk (They (Nokia) do after all own the flashers and firmware. It is their's to do with whatever they want...up to and including taking access of it away from us.) by perpetually posting or hosting links here or elsewhere.

#2- Ask individuals for help....privately

#3- And/ Or... as others have pointed out....
Contact Nokia and ask them to please rehost what we need.
Enough voices may help to have an impact and resolve this.
