We would like to move away from Google Code to something like Redmine or Trac, but then we'd have to host the solution ourselves. Since we're a globally used open source project, we need the issue tracker to be reliable (in terms of responsiveness) when accessed anywhere in the world.
So I figured cloud computing is probably a good solution (in terms of cost-effectiveness), but what issue trackers will work on cloud hosting? Usually they have their own APIs and platforms, so I have a feeling you can't just use something like Trac, or can you?
