Salesforce.com goes offline again and again

Several disgruntled Salesforce.com customers took their complaints to the blogosphere this week after enduring a series of recent outages, including one on Monday that reportedly knocked portions of the site offline for several hours. One anonymous critic has even set up a blog "for frustrated users of Salesforce.com", called GripeForce.

The GripeForce blogger wrote on Monday: "This is starting to happen all too often. From 10:30 a.m. through lunch, Salesforce was down. This is too much. Two days left in the month and the sales team can't access their data."

Concern about the reliability of the company's "on-demand" business application is understandable. Salesforce stores critical customer and sales information for thousands of businesses and delivers the data "on-demand" via the web. That means Salesforce users are at the company's mercy, a point brought painfully home last month when an outage disabled the Salesforce service for the better part of a day.

Monday's "episode" was less severe, according to Salesforce chief Marc Benioff. It lasted about 30 minutes and caused intermittent disruptions for some customers in the US and Canada, Benioff wrote in an email on Monday. He classified it as a "minor issue".

Yet customers are becoming increasingly frustrated. Mike Sax, an entrepreneur in Eugene, Oregon, wrote in his blog: "As a Salesforce.com customer, I am very disappointed by [Benioff's] statement.

"I am willing to put up with growing pains and an occasional outage. I am even willing to forgive that in terms of reliability, Salesforce has clearly over-promised and under-delivered. Having the company's CEO minimise an outage that brings customer businesses to a halt as a 'minor issue' is not acceptable."

Bill Bither, a Salesforce customer in Northampton, Massachusetts, didn't think Monday's outage was so minor either. He said it disabled a critical application programming interface (API), a mechanism that shuttles Salesforce data to other business systems, for seven hours.

Bither, a founder of software maker Atalasoft, wrote in a blog post on Monday: "We use Salesforce.com and have invested a lot of time and money into this system. Although the features and functionality is great, we're not very pleased with the reliability. Today, Salesforce.com was down from 11:30 a.m. until 6:40 p.m."

After customers began venting online, a Salesforce representative took a more contrite tone about the incident: "We know that any time that the service is not available, it's frustrating to our customers, and we sincerely apologise for that. We know that what our customers want is constant improvements in our service, and that's what we are working on today and every day."

Salesforce's availability rate is about 99 per cent, executives there say. They've blamed recent glitches on a database software bug, and recently detailed steps the company is taking to bolster reliability. Still, outages and downtime are an unavoidable reality of computing, Benioff said earlier this month.

In the meantime, Salesforce customers appear to be growing more vocal. One anonymous blogger purporting to be a Salesforce user posted four entries on Monday. "What Beautiful Irony!" the blogger wrote. "The day I decide to start this blog, SalesForce.com has another outage! Sheesh!"

Salesforce seems to be taking its customers' gripes in its stride. The spokesman said: "Our customers are entitled to their opinions and we respect that. When you have a passionate community of users, feelings are bound to run high."
