Facebook's BIG Software Failure
1,028The Facebook crash was a big software failure, and headline news, but what caused it? On Monday Facebook, Instagram and WhatsApp all went down. The Facebook outage affected people all around the world. This was widely reported as a configuration mistake, and it was, but it was also a more complex failure than only that. Big systems are complex dynamic things, and fail in ways that are difficult to predict, but we can learn a lot from this, and other failures at Facebook.
In this episode well known software developer Dave Farley looks at the Facebook software issues at the root of two different outages in 2021 and analyses what went wrong and what lessons Facebook, and other software development teams, can learn from these incidents.
