    Fastly distributed software that was not adequately tested, and one customer helped then find the bug. It is not the best case scenario, but at least it gets fixed.

      If architects built houses, they would kill the occupants in the first week. If engineers built houses, the owners would kill themselves within the first week.

      • I had a good friend studying to be architect, my sis studied to be a civil engineer (the latter doesn't make projects herself, lost contact with the former). In one conversation, I got told that architects do drugs and produce good-looking plans that the customer likes, then the civil engineer has to re-do the plans mostly from scratch to make them physically realisable and to allow the building not collapse the moment scaffolding is removed.

          If houses were designed by engineers there would be no challenge. The engineering challenge is in making possible the crazy things architects dream up. Engineers dont hate architects, they just like to cuss them but secretly enjoy the challenge of making real the crazy things people dream up on mushrooms.

            Then the contractor comes along and has to convince the engineer that what they speced is very difficult or costly to build and hope the engineer will change the design to make it more buildable.

            Case in point (where perhaps the engineer should have made a change, but obviously not the change they did make!) is the situation that led to the collapse of the catwalk at the Hyatt Regency Kansas City almost exactly 40 years ago (on July 17, 1981) which killed 114 people and injured over 200 others.

      If houses were built like software you'd be able to revert to the last stable version, civilization wouldn't have much more than a couple hours of downtime before being back up and running like nothing happened.

        Well, except for the houses that collapsed and killed the occupants before the problem could be traced to the bad revision (and assuming that the database under the house hadn't been modified by the new revision and the old revision would no longer work correctly as it hadn't been tested on the new database format/field contents).

    Or more colorfully, like Scully in the X-Files (forget the specific episode) in an autopsy (when she had a shot of histamines) she is asked "So what killed him?"

    "Bee....eep!" and Scully smacks her hands. Yeah he got mowed down by a bus as cause of death. That was the bug in this case.

    While I suspect any post mortem they could post would be beyond an outsider's ability to really make sense of, I would be really curious to read about how exactly a valid configuration change took down a whole system. I could understand if it was something silly like 'customer requested -1 CPUs and the parameter went through an unsigned field then tried to allocate billions of CPUs to them!', but what kind of valid change results in such a cascade failure?

      That's the first question I thought of. How can one customer, making a valid configuration change on their network, have a global effect on Fastly's entire network?

      If this explanation is actually true, it doesn't speak very well for the quality of Fastly's network.

        Because basic concepts such as segmented access, input validation, and TESTING don't quite go along with today's mantra of break things quickly.

        I will have to say, they did recover rather quickly. I wonder how many rubles, shekels, farthings, or florins were lost by businesses due to the approximate 1hr outage window?

        Can you imagine an explanation that speaks well of Fastly's network? I certainly can't.

      Probably something very stupid and very embarrassing that should not have happened in development at all and should most definitely have been caught in testing. You know, cheaper than possible software "engineering" at work. Hence we will probably never know. The lies have already started by claiming a customer caused it. In reality, a customer triggered it, but it was caused by Fastly.

      In some cases the outsourcing will improve quality because it results in code being tested better.

      Imagine if you develop your own locking primitives portable across several architectures vs. outsourcing that by buying a library that is consistently maintained (where "buying" may just be accepting a FOSS license). It's likely that the library you "buy" is much more likely to take into account an obscure error in stepping K of a three year old Intel chip and work around that shortcoming than your software wou
