Does http://mirror-status.centos.org/ show any issue with the mirrors you're being given by fastestmirror ?

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: Dependencies Resolved

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

External Mirrors sync at whatever period they choose. It could be daily or multiple times per day.

It can certainly take up to 24 hours for the majority of external mirrors to be updated.

Our script to verify mirrors can take 3-4 hours to run as well to develop a new mirrorlist.

Yesterday at 2200 UTC, we released 24 SRPMs worth of updates. That is a significant amount of information. (around 200 RPMs and 150-200 MB of info). Based on the 24 hour period I usually use, I would expect most mirror to be updated by 2200 UTC today (still 11 hours from now).
