Retrospective and technical details on the recent Firefox outage
It's a nice write up, but the "Lessons learned" is terrible, it appears as if they didn't learn anything and view the whole thing as an infrastructure problem.As others pointed out, why does Firefox even need to communicate with Mozilla services? Sure, telemetry needs to feed data back, if enabled, but if that fails why does it need to stop the browser from working?Shouldn't the lesson learned be: The telemetry functionality in Firefox has a bug, where an infrastructure outage at Mozilla can "break" the browser. The fix isn't in infrastructure, the fix has to be in the code that communicates back, it should fail gracefully. It's not a problem if telemetry fail, either cache locally and just drop the data, it's honestly not important.I'm sorry, I get that it's interesting how and why all this failed, but Mozilla makes it seem like they don't get what the root of the problem is.
