Hi,
there is outdated mirror CZ sunsite.mff.cuni.cz.
It looks like it was last updated at 23-May-2014.
It is causing lot of delays for me when updating FC20 using yum
update, because it is somehow preferred for me (in Prague, CZ).
Could you, please, remove it from mirrorlist or fix it to be sync.
Thanks
Milan Slanar
