I wrote a blog post that may interest computer geeks / IT admins with this subject:
http://www.redsquirrel.me/2008/12/uptim ... ume-2.html
What triggered me to write this post is I've seen so many instances where I've seen people bring a service down when really, it could be avoided.
Discuss.

1) People don't always have test servers on hand that they can try the upgrade on.
2) Some applications/situations require the upgrade of massive amounts of data that take a very long time. It is also not feasible to make a separate system with a mirror of all this data.
3) Sometimes the people administering the upgrade are retards and/or don't know wtf they are doing.

A test environment is a must though. In fact that should be the first thing to be setup before the actual live one, as the whole thing has to be tested ahead of time anyway and be developed. It can't really be done in thin air. So you keep test environment afterwards then use it to do your development on and test new changes/updates without impacting possible customers (depending on the system in question). Like when I make a website from scratch I always do it on my local server and test it from there so before it's even gone live I already have a test environment for it.
Even large sums of data should not take THAT long to transfer/change if the process is well coded.
