Hello Dear Ubuntu Team

English is not my first language, excuse me for mistakes

Our mirror ( CD and archive ) sync every 4 hour

But the status of our mirror in launchpad.net is "Last update unknown"

I send for you the last log of sync script that your team suggest

and the log of Archive

I do not find out , what is problem ??

Thank you for your Help , Thank you for your consideration
