Cloud services have ballooned in recent years, and that growth shows no signs of slowing. But the cloud has had its share of bumps in the road — er, sky.
A Brief History of Cloud Failures
T-Mobile Sidekick mobile phone users are left without access to their calendars, address books and other aspects of their service in a six-day outage of Microsoft servers.
A 30-hour outage strikes Google apps and Gmail after the services were interrupted by another outage just two months prior.
Quora.com, Reddit.com, GroupMe.com and Scvngr.com are affected by a more than day-long disruption that leaves many of the sites completely inaccessible.
An East Coast storm pulls the plug on some of Amazon’s servers in Virginia, causing outages in Instagram, Netflix and Pinterest.
Amazon’s own home page is knocked offline for about an hour; the company is said to have lost about $5 million in revenue during the outage.
Microsoft’s Office 365 editing suite and Outlook.com mail service both drop offline for a couple of hours, and the following day, the company’s Bing search engine has a brief outage of its own. A few weeks later, Microsoft’s Azure cloud storage service fails and its Xbox Live system keeps users from accessing cloud-connected data.
CloudFare’s own site and all of its services were knocked off line, taking down more than 750,000 other sites, including Wikileaks, 4chan and some government sites.
Amazon’s cloud computing service is hacked, exposing hundreds of thousands of LinkedIn’s 259 million member profiles to hackers.
Twitter is inaccessible for about 45 minutes.
Verizon’s Terremark cloud service suffers a network failure, causing the already troubled HealthCare.gov site to go offline.

Biggest risks of cloud computing
- No Internet connection means no access.
- Putting all your faith in the cloud means putting all your faith in continued, unfettered access, which will cost and continue to cost more.
- Intellectual property issues. Who owns the data you store online?
- Data might not be cloud worthy (i.e. customer-sensitive information).
- Companies and users have to trust their cloud service vendors to protect their data from unauthorized users.
- Cloud-based solutions are exposed on the public Internet and are thus a more vulnerable target for malicious users and hackers.
- Potential outages and downtime
