You're probably right, that's indeed the perspective I was (maybe subconsciously) looking for as well. I should also empathize a bit, I had to debug a prod outage early Monday morning.
I think it's the fact that I was in the middle of some job-change-related communications that also gave me nerves. Generally my email reliability requirements are not very intense!
Overall I've been happy even with some of the things I've seen complaints about (Fastmail iOS app has been great for me despite mixed reviews). I'll give Fastmail more time before making a judgment.
(And indeed it looks like it's back online for me.)
