Cowboys?
I work for the NHS doing 2nd line desktop support based at The Causeway in West Sussex.
I visit the server rooms hereon a daily basis to do various tasks, backups, patching ports etc.
All the server rooms I have had to visit so far have had very efficient cooling, most of them at least 3 air conditioning units. Although they do run a few servers with the covers off so air flow on those particular ones probably isn't too great, but it's within safe levels.
In our office we often joke about our colleagues being cowboys for whatever reason but we do a job and we do it well. Do the guy's at St. James's actually employ professional cowboys? It makes you wonder.
