The Frankfurt mirror is syncing correctly, so it seems your local database files were corrupted. Change back to the Frankfurt mirror if you prefer and run:

sudo pacman -Syy

Or use any other mirror close to you. You can also use the included rank mirrors tool to see which mirror performs best for you:

rankmirrors -n 4 /etc/pacman.d/mirrorlist

this command will result in listing the best 4 mirrors for you.

Thanks Demm for your prompt response. I wanted to remove a package (conky-manager) that I installed from KCP repo. I googled & followed this tutorial : http://www.linuxandlife.com/2011/12/right-way-to-uninstall-software-in-arch.html

After successfully uninstalling the packages I tried the command: sudo pacman -Scc just to test the features of pacman. After running this command when I run the following commands, the result is this:
http://pastebin.com/nvGbgY49

then I screwed up the mirrors list by altering the servers. The current content of my /etc/pacman.d/mirrorlist is this:
http://pastebin.com/nRpwATEU

Any hints on how to reinstall/recover the default mirrors list please?

Re-install the package pacman-mirrorlist
Then the original mirrorlist will be set as pacnew in /etc/pacman.d/, just merge/copy over.

Thanks Demm it resolved the issue:
sudo pacman -S pacman-mirrorlist
