It also depend the position you have in the mirror process, for instance is 
just one as another for Centos, anoying but harmless if it is down for 12H, 
but for mandriva it is one of the top level from which other official mirror 
sync from, in this case, two hour is already too much...

The second point is the size of files always increasing, at least more than 
the bandwidth we can usually provide. Three years ago, all distro was 
distributed as CD iso, now all come as DVD iso, download become longer. It 
often need a full day for several people to download just one image w/o any 
chance to just completed the download.

But hey, that's the life. And you'll never be able to provide a 24H a day, 365 
days a year service, disk can always crashes, big power failure (this has 
happend to us recently, the whole university in dark), etc, etc...
That's probably one reason there are several mirrors in the world :)
