Sure.

There are some interdependencies, which we should review carefully, and
minimize where possible.

* download.opensuse.org redirects (since recently) to the web frontend 
  on software.opensuse.org for requests to '/'. Requests to '/*' go to
  the downlaod redirector. As far as availability of e.g. the update
  repository and other repositories is concerned, it doesn't depend on
  software.o.o. 
  
  The redirector depends on a mirror database server, but can live
  without it for a certain period, until the network connection is
  sufficiently congested so it becomes to slow to respond. The latter
  effect can be mitigated somewhat by fallback mirrors to redirect to in
  the error case (to be implemented).

  Did we experience any availability problem since the current
  redirector is in place (about March)? I can't remember of any outage
  of the "over the weekend" kind...

  I can assure you that I'm against all infrastructure changes which add
  more dependencies than necessary :-)

* software.opensuse.org relies on the availability of the internal
  buildservice backend, for the search and ymp generation. Thus, when
  the buildservice hangs, the software.opensuse.org search hangs as
  well. This is unfortunate IMO, but I don't know if there is a way
  around this.

  I don't know if YaST/zypper depend on the availability of
  software.opensuse.org or the search on software.opensuse.org. If so,
  how? For ymp generation?

* software.opensuse.org/repositories/ redirects straight to the
  redirector. This kind of redirection is what is (should) only be
  happening when this obsolete URLs are used. Obviously, it can only
  work if software.o.o is responding at all.
