Gmail: Ultra-Reliable, Not Reliable Enough
By Bizbox
We are huge fans of cloud computing: the use of software that lets you do your business in the "cloud," such that your data exist (securely, ideally!) not on relatively inaccessible hardware but on the Internet--in the "cloud"--in a place where those who you want to access it can. It lets you, the entrepreneur, run your business more cheaply and bring geographically disparate people together on a single project more easily; it can even make your business doings more secure. Numerous folk have identified cloud computing as the future. (Even Microsoft's getting in on the action!)
The most basic example of a cloud computing software is Google's email server, Gmail--this is why we love it so much, along with Google's attendant suite of cloud computing applications such as Google Docs (a word processor), Google Calendar (a scheduler), and Google Reader (an RSS device)--your personalized versions of which all can be shared among as many people as you would like.
As we've said, one concern with cloud computing is the security, which can be scary. Another concern, however, is that the administrator of the cloud can, whether through error or deliberate decision, make the cloud inaccesible to you (or to everyone) on a whim. We've written before about the awful experience that is--gasp!--losing access to your Gmail. So you can perhaps understand why, when TechCrunch reports that Google insists Gmail and its other applications have 99.9% availability--in other words, you can't access them for a cumulative total of about 15 minutes per month --we're left not thrilled at this exceptional record but dreading that .1%.
The post refers to the legendary August Outage, during which all users lost Gmail access for about two hours. (You remember this, right? We know we do.) Apparently, two weeks ago there was another outage that affected far fewer but lasted over a day (shudder). Hence Google's new 99.9% guarantee, extended to Gmail and the rest of its cloud apps. (Although those 15 minutes per month are not necessarily consecutive, and if experience dictates, most of those "outages" last no more than about twenty seconds.)
We should note--Google certainly does--that Gmail has a fraction of the downtime of the email servers of competitors GroupWise, Lotus, and Exchange, all of whom unlike Google have planned downtime in addition to unplanned downtime. Gmail is has one-fourth just the unplanned downtime of Exchange, which is the mail program of this small company.
Still, as TechCrunch puts it: "99.9 percent reliability is nice. But that is not even phone-company reliable. Get back to us when you get to 99.999 percent." Amen.

Last week 236 of my fellow marketing bloggers and I launched a very ambitious project. The second of its kind, it was a collaborative effort to write a book about the new world of media we are all living in, which the book aptly calls the "Age of Conversation."
There are certain things that people simply won't give up, the thinking goes, and some of those things--because people need a release valve during tough times; because some people have nasty compulsions--are vices like gambling, drugs, and prostitution, which is how Tony puts his family in that lovely house in Essex County.
You can see this in the National Federation of Independent Business's
Small business owners are independent, have confidence in their own abilities, and are entrepreneurial. So the results of the recently released
From the start, they chose a paradigm to define the election by--change versus more of the same--called themselves change, called the other guys (whether it was Hillary Clinton or John McCain) more of the same, and then stuck to this paradigm and their preassigned roles without mercy. It was an utter constant. No wonder
No, not candidate Barack Obama the social-networker. President Barack Obama the social-networker.
