4th time we've run the CTF (sometimes as Cisco/Portcullis, this year as Team Alpaca)
106 challenges
Bandwidth usage so far peaked out at 24.4Mbps and disk usage at 19.4MB/s
Time machine challenge resulted in single CPU being pegged at 100%, required reprovisioning (x4 vCPUs) - go Ansible/Docker!
43 teams registered including one person playing over the Internet on their own (currently in 3rd place)
401 right submissions
507 wrong submissions
Jonty was yet again an item in the scavenger hunt category - sorry Jonty :)
We also caused uproar in the HAM community over "parabolic antenna"
We included a badge challenge for the first time

x - RouterOS
        Core vs optional
        Linux so supports various architecture
        2.9 added /nova/etc/devel-login
                If this exists, devel/<admin password> gets proper shell
        Anatomy++ created createnpk.py and dumpnpk.py for 3.x
        3.22 added checksums and signing
        supout.rif contains
                Configuration
                /proc/

lquerylv_fix/ecfile:    TARGET_FILE=/usr/sbin/lquerylv          - this is likely the "same" fix as in lvm_fix, i.e. a regression
lsmcode_fix2/ecfile:    TARGET_FILE=/usr/bin/bsh                - not worked out what the relates to, i reckon there is another bug...
lsmcode_fix2/ecfile:    TARGET_FILE=/usr/ccs/lib/libc.a         - this is likely a fix for a regression from malloc_file
lsmcode_fix2/ecfile:    TARGET_FILE=/usr/ccs/lib/libc.a.min     - this is likely a fix for a regression from malloc_file
lsmcode_fix/ecfile:     TARGET_FILE=/usr/sbin/lsmcode           - not worked out what the relates to, i reckon there is another bug...    
lvm_fix/ecfile:         TARGET_FILE=/usr/sbin/lquerylv          - this actually fixes a bug in DBGCMD_LQUERYLV
malloc_fix/ecfile:      TARGET_FILE=/usr/ccs/lib/libc.a
malloc_fix/ecfile:      TARGET_FILE=/usr/ccs/lib/libc.a.min
  
FWIW: this is why I think the lquerylv patch and lvm patch are identical, they patch the same file and from a quick check the more significant change
