problems with mirroring cron-job

[ariel sabiguero yawelak]

Hello. Some days ago we started getting:

    Could not sync from rsync://mirrors.kernel.org @ERROR: max
    connections (75) reached -- try again later rsync error: error
    starting client-server protocol (code 5) at main.c(1672)
    [Receiver=3.1.3] @ERROR: max connections (75) reached -- try again later


from our tier one mirror. We wrote them but no answer yet.
Last night we got a "slot" to the rsync server but:

    find:
    ‘fedora/linux/development/rawhide/AtomicWorkstation/x86_64/os/EFI/BOOT/.~tmp~’:
    Permission denied find:

    aborting run. Will not check in or delete anything.


Is it only us or there are others getting these problems with upstream 
servers?
Should we do something?
