While I appreciate the general principle that many others have also observed, that one should assume bugs are in one's own code before blaming the underlying system, I find that this is often an excuse to avoid understanding the problem and applying the solution where it belongs. The operating system, the network, remote APIs, and other infrastructure often are the problem, and if you don't invest in building and understanding tools that can truly explain what's going on, you often and up building crappy workarounds for shortcomings in the underlying infrastructure.
