My mirror has that, as would my upstream mirror, mirror.es.its.nyu.edu. I suspect it's related to an earlier mentioned issue in switching upstream servers.

It seems that almost all mirrors have a broken lastsync file, whose contents solely consists of the string "/bin/sh" instead of the usual UNIX timestamp.
Is this a known issue?
Thanks in advance!
