Agreed. Nobody in my office is having issues, but I know one guy whose cowork space is full of pop-ups on their computers, complaining over and over again about not being able to access iTunes or something -- when they're not actively trying to use any service. I'm guessing maybe that cowork space NATs out as the same IP which is why all workers in one office would have issues but I haven't heard of these issues in my own office or other friends' workplaces.

Hopefully this fiasco teaches them a little about being less obtrusive with such messages. In the past, it likely could be chalked up to a user misconfiguration, so they can blame a PEBKAC issue and push it on the user. When the failure is on Apple's end, and it affects many users at once, they'll hear pretty loud and clear that these need to go away.
