Mirror load is the issue.  May 20 was in the peak download of FC2.  Add
to this a slight bit of confusion because of dynamic mirror selection.

If you watch up2date you will see dynamic mirror selection.  Some are
silly.  With a default config I saw a connection to a small European
site that was slow.  Killed it (I am in California) and  on restart it
connected to a US mirror and the update went quickly.

I suspect that some sort of smarts needs to be invented for improved
locality. If I understood this better I could file an enhancement
request.  Perhaps a cookie could pass time zone info

Simple arithmetic can then look for a match.  If no match then widen the
search +/- 1,2,3,5,both NS,8,13, any).
