With things setup the way they are - network distance from debuginfo to 
the head-node is ~ 400KiB/sec which means that sometimes it takes a very 
long time to sync the debuginfo's into the right place. eg. the sync for 
5.3 started on Sat morning, its about 35% of the way through.

Something to definitely consider / reconsider.

Change which part ? signing them or automating something ? The reason 
debuginfo's are not signed is that bringing them into a securebox for 
the signing process and pushing them out again easily triples the time 
factor.

At the moment, there are 2 internal and 1 external mirror for debuginfo 
- that can be increased if required. I know that atleast mirrorservice 
and kernel.org have previously said that they will make more space 
available to centos.org if we need it on their mirrors - and they are 
happy to host vhost's for debuginfo / beta's.
