If you missed that Google had a 2.5-hour Gmail outage yesterday, you were probably hiding under a rock, or possibly in one of those sensory deprivation chambers. Every major tech blog and news outlet was on it (not to mention Twitter users).
It was night-time in the US, which limited the impact there, but the rest of the world wasn’t so lucky. For example, in Europe the outage started at 9:30 in the morning.
Loss of productivy costs… how much?
A lot of companies use Gmail, and while for some the temporary lack of email service may not have had a big impact on business and productivity, for others it must have been a real problem. What could an outage like this actually cost Gmail end users?
Google has put a number on it: It was worth 15 days of free service (if you’re a paying customer, that is).
Considering each license costs $50, that comes down to the equivalent of $2.05 per license. Still, Google is being generous. If they had followed their SLA strictly, it would only have come to 41 cents… (Pointed out over at GigaOM.)
A few lessons learned from the Gmail outage
The Gmail outage yesterday showed us a few interesting things.
- Email is far from dead. You only notice how much you use it once it’s gone.
- If a service as widely used as Gmail goes down for a decent amount of time, the blogosphere and press will collectively go gaga.
- If Google is involved, the effect in the previous point is multiplied by 2.
- Not even Google is immune to long outages.
- Murphy’s Law is alive and well.
Google’s explanation of what happened
We brought up Murphy’s Law, and that pretty much sums up Google’s explanation of what caused the Gmail outage:
Lots of folks are asking what happened, so we thought you’d like an explanation. This morning, there was a routine maintenance event in one of our European data centers. This typically causes no disruption because accounts are simply served out of another data center.
Unexpected side effects of some new code that tries to keep data geographically close to its owner caused another data center in Europe to become overloaded, and that caused cascading problems from one data center to another. It took us about an hour to get it all back under control.
There are simply so many factors involved in providing a large and complex service that eventually something is bound to go wrong. And clearly, no one is immune to this. Not even Google.

In 2010, there were just over 1 million secure Internet websites worldwide. Almost half of those, or 446,992 to be exact, were located in the United States.
But in which country can we find the most secure websites in relation to population? The answer may surprise you.

The New England Patriots held what seemed to be a commanding lead (17-15) with five minutes left of Super Bowl XLVI last night. But the New York Giants came back and managed to win with 21-17.
As exciting as the game sounds, we missed the whole thing, instead spending our time watching the Superbowl.com website.
It turned out to be a rather dull thing to do because the site held up well and there was no downtime at all. The response time also didn’t give away anything significant in terms of online Super Bowl traffic.

Out of the 59 US-based e-commerce sites we monitored during the holiday season last year 28 scored a perfect 100% uptime for December.
Whether this helped spur on the booming sales in the US, we don’t know, but retail e-commerce spending in the US reached $37.2 billion for the November to December 2011 period. That was an increase of 15% from the same period in 2010.
We decided to dig into the numbers for these e-commerce sites to see how well they did in terms of uptime and performance. After massaging the data coming from our Pingdom probes, it turns out that the sites overall performed well during December 2011 in terms of uptime, but response time was an issue for several sites.

What about a number on the documents that they shared with others? Like business plans etc with all figures including revenues. That has to be worth more than $2!!
