Don't You think guys the server is too much times updated? Everytime (every update I mean) after the update we got a lot of troubles (including additional downtime, not working for a while some services they were working before update etc.).
Instead inceasing the security by instantly update the server (if any new software appears for it), maybe just focus on making good backups of the server to get it back to work if someone really destroy it (because it is not 100% safe because of not installed some new stuff). I guess restoring the server from the backup is less troubles and shorter down-time than all down-times we need for every update.
I'm not any expert of servers, so I can't say You "do it - it's good" - or "don't do it - it's bad", but having some experience browsing other forums I may attest - our forum has the longest down-times from all I'm browsing. Dunno - other admins (of other forums) probably don't care so much for every update and their servers aren't attacked so often (I really don't remember any bigger down-time of other forum because got attcked/hacked), but - as the most important fro me - they just work.

"Something better is always an enemy of something good".

That's my opinion.
