I've written briefly before about the value of companies being open and transparent. Back then, I wrote that the way that companies react when things go wrong is a good way to differentiate between them. No matter what company you deal with, things will go wrong at one point or another. Some companies try to avoid responsibility, or only tell you that something has happened if you ask them. Others companies are much more open about what happened.
Matrix.org (and the associated Riot.im) is an example of a team that falls into the latter category. And last night's incident is a good example. Their post-mortem blog post is a great example for others to follow. It gives a detailed timeline of what happened and why the outage occurred. And it finishes off with steps that they will take to prevent future incidents.
Kudos to the Matrix.org team for their transparency.
