Microsoft brags about Office 365’s 99% uptime, is trustworthy and reliable


In an official blog post today, Microsoft is celebrating and even bragging a little bit about the company’s Office 365 cloud service. According to Microsoft, Office 365 has seen a 99% worldwide uptime, nearly matching the company’s promise of having a 99.9% uptime promise.

“The worldwide uptime number for Office 365 for the last four quarters beginning July 2012 and ending June 2013 has been 99.98%, 99.97%, 99.94% and 99.97% respectively. As a commitment to running a highly available service, we have a Service Level Agreement of 99.9% that is financially backed,” Microsoft stated in an official blog post.

According to Microsoft, this uptime number includes Exchange, SharePoint, Lync, and Office Web Apps and the percentage was weighted on the number of people using each of these services. Office 365 customers tend to use most if not all of these services together, which is factored into the uptime percentage number. Microsoft did not factor in Office 365 ProPlus, since this software mostly runs locally, rather than via the cloud.

However, even with a 99% uptime guarantee, there can always be hiccups along the way. Microsoft promises that if a service interruption occurs, the company does a through post-incident review regardless of how serious the downtime was. “A post-incident review consists of an analysis of what happened, how we responded and how we prevent similar incidents in the future. In the interest of transparency and accountability, we share post-incident review for any major service incidents if your organization was affected,” Microsoft added.

Microsoft even added that the company uses their own products and pre-production service to conduct daily tasks. Microsoft aims to provide continuous improvements, as well as a highly available and world class service with Office 365.
