Google has an Apps Status Dashboard website where users of Google Apps such as Google Mail, Google Talk and even Postini services can see current service status. This replaces the previous dashboards or stoplight service reporting function for these services. You can even subscribe to an RSS feed for tracking service status. Check it out. Scroll back through older status reports and see what services had issues and when they were resolved. It might help you in making a decision about how reliable Google apps are for your organization.
Thanks for reading & let’s continue to be good network citizens.
