Comment on CrowdStrike downtime apparently caused by update that replaced a file with 42kb of zeroes

The file is used to store values to use as denominators on some divisions down the process. Being all zeros is caused a division by zero erro. Pretty rookie mistake, you should do IFERROR(;0) when using divisions to avoid thay.

I disagree. I’d rather things crash than silently succeed or change the computation. They should have done better input and output validation, and gracefully fail into a recoverable state that sends a message to an admin to correct. A divide by zero doesn’t crash a system, it’s a recoverable error they should 100% detect and handle, hot sweep under the rug.

  Life pro tip: if you’re a python programmer you should use try: func() except: continue every time you run a function, that way ypu would never have errors on your code.

IFERROR(;0)

Maybe they should use a more appropriate development tool for their critical security platform than Excel.
