Today its the turn of iMessage and FaceTime, two of the better services that Apple offer, to drop offline.
For services which have actually become key parts of some users communication armoury being offline for close to five hours (as of 11.30AM, NZT) is very poor indeed.
This would be an excellent opportunity for Microsoft to make a big push behind Skype, but for yesterday's news of the Skype Bitcoin mining trojan attack. At the moment Apple's flakey service looks a better bet than Microsoft's security challenged one.
