Mirror not synchronized since January

[Henry-Joseph Audéoud via arch-general <arch-general@xxxxxxxxxxxxxxxxxxx>]

Hi all,

Today, I discover two machines not having same version of one package. 
Both are up-to-date (just did a `pacman -Suy`).  But they do not use the 
same mirror.  Indeed:

    $ curl -s -I 
'http://archlinux.de-labrusse.fr/core/os/x86_64/core.db' | grep -i

I understand there may be a little time gap between mirror synchronize 
themselves.  But 19 January seems far from today.

Is this expected?

P.S.: I did not checked other mirrors.
