4. Google Apps, Google Talk, Go Down
Google, like every other cloud services provider, said it takes every measure possible to keep its service up and running. But, like the others, it suffered from outages in 2012.
Google was victimized on Oct. 26, when Google App Engine, the platform for developing and hosting Web applications in Google-managed data centers, lost service for about four hours, suffering slowness and errors. As a result, 50 percent of requests to the App Engine failed.
Google said no data was lost and application behavior was restored, and that the company will bolster its network service to fight traffic latency.
Google Talk, the chat service used by Google Gmail customers, went down for almost five hours on July 27.
