Google's popular Blogger blog-publishing service crashed early on Friday and remained unavailable to most users for about 90 minutes, the type of broad system outage that Google has been trying to eradicate from its Web-hosted applications.
The statements didn't offer an explanation for what caused the outage, which lasted between approximately 2:10 a.m. US Eastern Time and 3:40 a.m..
Google didn't immediately respond to a request for comment.
Millions of individuals and organizations use Blogger, a free online service, to publish and manage their blogs.
Google is a big proponent of Web-hosted "cloud" software, which the company argues is less expensive, easier to implement and maintain, and friendlier for workgroup collaboration than on-premise applications installed on users' PCs and servers.
However, cloud-computing skeptics worry about a variety of issues, including users' lack of control over the performance of cloud applications in cases when they crash or malfunction in other ways.
Google has pledged continued improvement in the uptime and reliability of its Web-hosted applications for consumers and businesses. This is particularly important as the company courts CIOs with its Apps collaboration and communication suite, whose Premier version offers a 99.9 percent uptime guarantee and costs US$50 per user per year.
Google cofounder and President of Technology Sergey Brin recently told reporters at a press roundtable that the company wants to up the Apps Premier service-level agreement to 99.99 percent uptime.
Last month, Gmail, which is used by individuals in its stand-alone free service and by companies of all sizes as part of Apps, had two widespread outages, while the Google News site also suffered one.
