In the 99% of cases where this status page is used, it is in fact the truth: we'd throw it up when we had e.g. data migrations to do as part of a rollout that wouldn't allow for our normal zero-downtime deploys.
So no, lies are not always quicker than the truth.
There's plenty to criticize Instructure about; let's not go reaching for straw men in the process.
That's just the quickest page/status update to throw up; it was a one-liner to push it live back when I was on the deploy rotation.
I'd hazard a guess they have more important things to worry about right now than exact status page messaging ;)
