I maintain a local mirror of the standard debian.org
repositories for squeeze and wheezy. I am finding lately that there are significant gaps in the Valid-Until entry for my mirror of the wheezy-updates repo.
I can trace this back to the fact that Valid-Until entry differs
What should my expectations be for mirroring ftp.us.debian.org
? If I were to mirror on the 64.50 entries every morning at 10h UTC, would I be guaranteed to have only a 1h gap in my local mirror?
My local mirror's previous entry expired at 08:58 UTC which is suggestive of a 3 minute period during which ftp.us.debian.org
did not provide a bugfix repository which self-declares as valid.
It seems to me that there should never be gaps in the Valid-Until provided by a primary mirror. That is, if the maintainers of the debian.org
repositories intend to update every 7 days, that the previous entry should be valid for 8 days. But I'll allow I haven't thought about repo management a whole lot so there may be good reasons to prefer a gap in validity to a repository declaring itself as valid even if it is slightly out-of-date.
I'm not sure if this problem affects other repos at debian.org
. I tried some simple google searches to see if this particular problem has been reported before, but I only saw evidence of what appears to be transient issues in the "Valid-Until" rather than something systematic like the above.
