To be perfectly honest with you, I wanted to come here to say that their services (on a good day) aren't very reliable anyway.
I routinely have email issues, file transfer issues (to icloud) and issues accessing their binary notarisation service.
The only thing that works routinely well is Apple Pay, however I think that it's refreshing a key lazily in the background and does not actually need a network connection to work. Good design at least.
So when I saw that they're having an outage, I thought. "All at once this time I guess".
I'll be really open here and say that I applied for an SRE job there out of hatred because whoever is in charge of SRE/Infrastructure Operations at Apple is doing a terrible job (or has terrible circumstances).
I've never had issues at all. I use their consumer offerings (iCloud, Apple Music, Apple TV+, Apple Arcade, etc.) and I've never personally witnessed an outage or problem. I regularly transfer stuff to iCloud from my PC running Linux, and I use the email service with a custom domain that used to live on Google until Google canceled the free tier of small business and also raised prices on the paid tier.
