Measure to manage. And eat your own dogfood

What we learned from 1 million businesses in the cloud:

We measure every server request for every user, every moment of every day. Any millisecond delay is logged.

More than 1 million businesses have selected Google Apps to run their business, and tens of millions of people use Gmail every day. With this type of adoption, a disruption of any size — even a minor one affecting fewer than 0.003% of Google Apps Premier Edition users, like the one a few weeks ago — attracts a disproportional amount of attention. We've made a series of commitments to improve our communications with customers during any outages, and we have an unwavering commitment to make all issues visible and transparent through our open user groups.

Google is one of the 1 million businesses that run on Google Apps, and any service interruption affects our users and our business; our engineers are also some of our most demanding customers. We understand the importance of delivering on the cloud's promise of greater security, reliability and capability at lower cost. We are hugely thankful to our customers who drive us to become better every day.
