Hello,
I have a CentOS 7 server, right installed.
I notice that some packages that are present  at
http://mirror.centos.org/centos/7/updates/x86_64/Packages/
are not present yet at some other mirrors (that are the ones my
fastestmirror plugin picks up... even after a clean):
http://centos.datente.com/media/7/updates/x86_64/Packages/
or
http://ct.mirror.garr.it/mirrors/CentOS/7/updates/x86_64/Packages/

For example packages like glibc, bash and dbus have updates dated 02 August
on the main mirror site but not yet at the other two sites.
if in Centos-Base.repo file, [updates] section, I use baseurl instead of
mirrorlist entry and run

sudo yum clean all
sudo yum update

I then get these packages' list:

Is this ok [y/d/N]:


What are typical delays in mirrors' sync? Or is there any problem in
mirrors updates?

Thanks,
Gianluca
