"We're reviewing all of our communications and service level measurements to identify areas of improvement," Microsoft BPOS official Morgan Cole wrote in an online comment. "One area of focus that we have is to build better tools to provide timely, accurate and targeted communications about service health." One customer had complained that on Sept. 7 the Microsoft administration site claimed the "services were 'healthy' during a time when the services were not accessible." Microsoft's Hotmail service also suffered an outage on Sept. 2 that locked some users out of their e-mail accounts for hours. Despite these recent service interruptions, Creese of Burton Group says cloud services may still provide better uptime than many organizations are capable of providing internally.
