This makes me feel a lot better. I needed to log into my apple dev account today for my once every 6 month check in, and absolutely nothing worked. I thought it was my account, my browser, my device, etc. But changing each of those, it still didn't work. But it appeared like it was going to load ......but still didn't. It was very bizarre. I just thought, surely Apple isn't having an outage the one time I actually need to do something.
It's definitely frustrating when Apple services go down unexpectedly. I also checked the Apple System Status page earlier, and it wasn't reflecting the outages at that time.
I found reports on Downdetector indicating issues with the App Store earlier, which was a relieve to me, lol. Apple's System Status page caught on some time later.
