It's the latest in a chain of outages that have hit a company that prides itself on the percentage of business coming from online applications. For example, the Intui Quickbase Facebook page says 700,000 applications have been developed utilizing the tool.

However, there was a 24-hour incident in early June that knocked out most Web applications and sites. That was attributed to routine maintenance that knocked out primary and secondary back up systems. Last week, Intuit reported that disruption to the commercial power supply triggered a nine-hour outage to most systems.

QuickBase had suffered some problems prior to the latest outage. There was a 10-hour period of degraded performance on Monday, July 19, followed by an outage of slightly more than an hour yesterday, according to an activity report on a QuickBase Web page. Users were complaining about outages as 4 pm yesterday July 20. It was not clear if the complaints reflected the previous outage, which appears to have ended about an hour before the latest episode began.
