Nicely written... I don't think I've read a more reassuring outage message before. Especially since it doesn't particularly sound like it's meant to be placating, it's just informing.
Thanks, but I wasn't trying to be reassuring, only to provide an explanation of what happened.
A good explanation is reassuring.
Still though, well-written and clear, as always. Kudos.
That's a big part of why it's reassuring. No dodging blame, no useless half-answers. That, and that your safety-first decisions existed at all and worked is excellent news to any of your customers.
