mirror-probe: "up to date check" is too fast

(I did not find a way to file a bug against the mirror-probe system, please move accordingly)

Dear all,

on the mirror status page (e.g. https://launchpad.net/ubuntu/+mirror/ftp.halifax.rwth-aachen.de-archive) I see information like "six hours behind" and "up to date".

Based on my observerations in the last few months, I sometimes noticed my mirror is regarded as not-up-to-date, although we synchronize a) with the official ubuntu rsync master mirror b) as often as it is stated in the wiki page on how to set up mirrors ("Keep up to date. Please try to mirror about four times a day (so every six hours) for archive mirrors. ").

You seem to check mirrors for files that were included on your master mirror only minutes or even seconds ago. In this case it should be fairly obvious that the file is not (yet) available on (non-pushed) mirrors.

I suggest to not check for files newer than six hours or let the mirrors synchronize more often than every six hours.

Thanks,
Carsten
