Even if it's just a five-minute outage, when Google goes down -- the Internet grinds to a halt. And on Aug. 16, Google.com did just that, with all services down for less than five minutes. In that time, reports said that the volume of global Internet traffic plummeted around 40 percent.
That wasn't the only time this year that Google services took a hit, however. Google Drive was down intermittently from March 18 to 20 for a grand total of 17 hours due to a glitch in the network control software. The outage impacted around one-third of Google customers. More recently, Gmail experienced a 12-hour outage on Sept. 23 from a dual network failure that hit around a third of its user base.
