Pretty ungenerous of you. I think that maemo is extremely luck to have a corporate sponsor who puts up with the criticism, justified and unjustified, that we all throw at it. Of course there is something in it for them, but the infrastructure isn't free. Trust me, Red Hat does help Fedora out of the goodness of their heart either. And HP has been a very good friend to debian.

Maybe we ought to have an official mirror service, not necessarily a bad idea.

Um, several gigs of debs and gigs of bandwidth is non-trivial. This will cost. And that is just repos.

Bugs URLs please. Hard facts please, stuff we can present to Nokia and say: "Akamai is not performing."

Keeping it in sync. Another resource to monitor, yak shaving, etc.

You undermine your argument when you become pejorative and dismiss out of hand the significant work being done. 

Plus there is lots of stuff happening behind the scenes. I agree that we should be more communicative about this, but it is happening.

Garage runs it all. The repos, the web site, gforge, etc. There are some other resources but nothing significant. This is all getting built out by an order of magnitude. But it takes time because obviously we want as little downtime as possible.

The repositories are a public resource. Nothing but time, cost and energy stop you from mirroring them yourself. Having an infrastructure to mirror different from Akamai might be good either as a redundancy measure or as an emergency resource. I think you'll find it non-trivial and your time will be better spent helping the new infrastructure and pointing out where Akamai fails to deliver so we can fix it.

Sounds like intentional Akamai magic.
