Not really.

Since July last year.

The worst I've had was the HP server shutting down in a 
London data centre due to environmental overheating.

Beyond that, similar requirements as with a router, if you 
avoid the VM clustering goodness they all preach.

Amongst very many other things, running an RR on my core 
router means I need to touch my core router code if I want 
that exotic routing feature.

I'd rather not, if my core router (in-path) is really just 
forwarding traffic between PoP's.

But agree, our networks are probably quite different :-).
