On Tuesday December 20th, some salesforce.com users experienced intermittent access (between approximately 9:30 am and 12:41 pm ET & 2:00 pm and 4:45 pm ET) on one of the companyĆ?s four global nodes. The root cause of the intermittent access was an error in the database cluster. Salesforce.com addressed the issue with the database vendor. By Tuesday afternoon EST, the system was running normally for all users.What concerns me though, is not this single outage. It's that this is just the worst case incident in what is apparently a less-than-rare occurance for Salesforce.com customers. According to CNet:
Salesforce touts an "uptime" rate of greater than 99 percent. Outages are "a rare occasion," according to [Salesforce.com spokesperson Bruce] Francis. He said Salesforce's systems are as reliable or more reliable than other comparable systems, including the type that companies run on their own servers.It doesn't need to be this way. A large part of what Google and Yahoo provide is really software on-demand--little applications. When was the last time you went to Google or Yahoo and found service unavailable for more than a few seconds?
Yet several Salesforce customers that contacted CNET News.com about Tuesday's glitch said outages happen more frequently than they had expected. About once a month, Mission Research experiences Salesforce outages that typically last an hour or so, [Charlie] Crystle, [CEO of Salesforce.com customer Mission Research] said. Another customer, an East Coast consulting firm, has been struck by outages about a half a dozen times over the past year, according to the firm's vice president, who requested anonymity. Frustration levels are rising.
"I'm really, really angry about this because (Salesforce is) out there marketing themselves as something they're just not living up to," Crystle said.
Readers of the Spectator know that I'm actually a proponent of the trend toward software on-demand. I like its promise to simplify system implementation and maintenance, especially for small and mid-size businesses, relieving the customer of having to worry about things like backups, recovery, disaster planning, and service level maintenance.
But the trend toward software on-demand is going to be set back several years if on-demand vendors can't maintain the service levels they promise and that customers expect.
Are the problems of Salesforce.com typical of other software on-demand vendors, or is Salesforce.com an anomaly? If you have insights, post a comment to this post or email me.
Update, Dec. 22. There's further discussion going on in the comments section for this post.
