Microsoft apologised to customers of its hosted software services for businesses after at least three outages over the past few weeks.
"We aspire to deliver quality services, and in the last couple of weeks, we have fallen short of this aspiration," wrote Morgan Cole, who said he is responsible at Microsoft for making sure that Business Productivity Online Suite customers have a good experience. "I wanted to write here to apologise to you, our customers, for any inconvenience these issues may have caused." His blog post appeared at 10:30pm US Pacific Time on Wednesday.
He referred to three recent issues that customers may have had accessing the BPOS services, which include hosted email, SharePoint and web conferencing. On 23 August, upgrades to network infrastructure caused "unforeseen problems that affected access to some services," he wrote. For about two hours, customers served from Microsoft's North America facilities may have had trouble accessing the services.
While engineers addressed that issue, their efforts didn't resolve another underlying issue that created additional problems on 3 September and 7 September, he said. On those days, customers may have had trouble signing in and using the administrative portals. There was more "widespread customer impact" on Tuesday, however, although for a relatively short period, he said.
"We appreciate the serious responsibility we have as a service provider to you, and we know that any issue with the service is a disruption to your business - and that's not acceptable," he wrote.
On the blog post, a commenter identifying himself as Guy Gregory, a technical specialist at Peak Support Services, said that the two-hour outage caused August uptime for the service to dip to 99.7 percent, below the 99.9 percent uptime guarantee. Microsoft offers money back to customers if it drops below the 99.9 percent threshold.
Microsoft did provide credit to affected customers, Jim Glynn, a project manager for cloud services at the company, said in a comment after the blog post. Customers who think that Microsoft didn't meet its service agreement and who didn't get a credit should contact support, he said.
On Sept. 2, Microsoft also had problems that prevented some Hotmail users from logging into their mailboxes. In his blog post, Cole said that the issues affecting BPOS did not affect any other Microsoft service.
Microsoft has sought to position itself as better prepared to serve enterprise customers than some of its competitors, like Google. But just like customers of Google's enterprise offerings, BPOS customers are complaining about a lack of information during outages.
Microsoft is reviewing all of its communications to look for ways to improve, Cole wrote in the comments after his blog post. "One area of focus that we have is to build better tools to provide timely, accurate and targeted communications about service health," he wrote. Currently, Microsoft has an RSS feed that offers updates when services are impacted, but some customers have complained that the updates are too vague and sometimes tardy. Cole said the company has already started adding features that allow it to add more details to those feeds.
