I got a reply a day or two later, telling me that it was perfectly OK for me to be doing what I was doing.

NOTE/DISCLAIMER: I too always respect such wishes of mirrors -- their bandwidth is graciously donated to them in some cases, and to us in all cases, so it may be best to err on the cautious side in this case. Since I believe I no longer have a copy of that email from them, I cannot prove that they said it was OK, so again, err on the cautious side.
I may have posted that email on LQ here somewhere, because that issue arose before, which *might* have been why I emailed them in the first place. Also, I took it to mean specifically the rsync service, as opposed to both rsync and other methods, but that may be a wrong interpretation. If you do come across it, please provide us the location.
Maybe I should email them again..

Anyhow, back on track: "-current repos", on any particular mirror, might be in a semi-available state at any given time, due to the mirror itself being updated at the very moment YOU are trying to download from it.
I dunno if this has ever happened to me, but so far so good as I am using OSUOSL's ftp server to upgrade to current as we speak. It's in the /xap/ folder right now.
