The  Compass

— Michael Raymond

Website software has a short shelf life. Because of this, your website can stop working overnight for no apparent reason.

First and foremost, the software that runs the web server where your site is hosted is continuously being updated. At least it should be.

Server software updates are designed to protect your site, your business and customer data, and the network of your hosting company. Those same updates can, on occasion, cause your site to stop working.

Every few years, new versions of most scripting languages are released. New features are added, old bugs—undocumented features in the programmer's lingo—are attended to and the potential to break something is greatly enhanced.

Either of these scenarios can be time consuming to track down and you will most likely be charged for the time spent in doing so. This does not fall into the category of "paying for somebody to learn" the software. Tracking down issues with errors related to software upgrades requires someone already familiar with that language, and the expertise to know not only the solution when they find it, but how and where to implement it.

Sometimes, you really should reinvent the wheel.
