All our Apple devices suddenly working very poorly

Is anyone else suddenly having huge problems with all Apple devices??

We have an iMac, 5 iPhones, 4 iPads and all of sudden we have problems with all of them, especially the iMac and iPhone 6 plus and iPhone 6.

The iMac photos and iPhoto app don't sync and photos I've taken with iPhone don't show up in iCloud.

Safari is constantly closing itself and/or stalling out unresponsive.

Many other issues...

It seems like Apple just suddenly screwed everything we own from them...
