Problems• No room for traffic bursts• FRAGILE - Don't want to upgrade X

because it may break Y.• Single point of failure - could shut down

our business for hours to days. • Encouraged manual "hacking". Rather

than run the proper build script, I'll just tweak this file on the live site. It's OK...
