A More-Perfect Cloud
There's a paradoxical dynamic taking place in the cloud—while outages have become less common, their impact is more widespread and damaging than ever.
Uptime has been improving, and will inevitably continue to do so, as cloud technologies mature and providers gain operational experience.
It's that incremental, steady progress toward greater reliability that's imparting enterprises, governments and academic institutions with the confidence to migrate mission-critical workloads whole hog to the cloud.
Which is why, even as some of the outages below weren't as catastrophic as those on incarnations of this list from years past, they created more problems, at times halting operations of entire government agencies and shutting down commerce for scores of high-tech businesses.
No provider is perfect, but those that host the bulk of the world's workloads are most worthy of scrutiny, which is why tech giants like AWS, Microsoft, Google, and Apple are so prominent on this list.
