My goal is to rework lore.kernel.org significantly. Currently, it's a 
single system hosted at AWS that both receives mail and serves the 
archives, but I would actually like to split it into two:

- the archiver that just generates git repositories but serves no 
  traffic (probably running directly on mail.kernel.org).
- several front-ends that replicate repositories from the archiver and 
  provide http/nntp access, probably reusing mirrors.edge.kernel.org 
  nodes that run from us-west, us-east, eu-west and ap-east.

That should provide both redundancy and better geographic availability 
of the service. This requires some testing first to ensure that 
grokmirror hooks and reindexing works reliably for replicated repo 
collections.

The number of people using nntp is several orders of magnitude lower, so 
I'm not sure it's a good metric for anything.

Best,
