Network Support Trueisms

This is a list of things that are inevitably true, written from the point of someone who has done network support for far too long.

    Your (IP/PING) packet may get there but that doesn’t mean it can get back.
    Subnet masks still matter.
    At a customer site you will either be standing around waiting or rushed off your feet. There is no middle ground.
    Requirements change often just before you hit return, and frequently after you have pressed return. Always get confirmation.
    Being blase bites backsides. If you don’t prepare, you will be caught out by something that otherwise would have been thought easy.
    Documentation and diagrams and descriptions are the lifeblood of support. Don’t set yourself up to bleed later by ignoring it.
    Early to rise and late to bed is what you should expect when going onsite.
