10. Google Docs Goes Dark
In September, Google Docs and a handful of other Google cloud offerings went offline for roughly an hour, making Google Document Lists, Google Documents, Google Drawings and Google Apps Scripts inaccessible for the majority of Google Apps users. Google quickly got the cloud services back up and running and said that the downtime was caused by a change that had been designed to improve real-time collaboration within the document list. That change, Google said, exposed a memory bug that caused the hour lull. Google Docs suffered another outage in October.
