How can I confirm when there is a server outtage? How can I see how long the outtage lasted?

We always regret when there is any loss of service to our clients, but it does happen occasionally. Our status page shows the current status for our servers in all countries. When there is a systemwide issue that affects all accounts, we will post about it here:
The duration of time between specific posts is not noted on the status page, but you can see the time the post was made by hovering on the line for the date of the post, right below the title of the post.
Also, at the bottom-right corner of that page is a Subscribe button. If you subscribe to the status page, you will be able to get emails relating to the servers that your account is on, whenever an incident is posted to this page, which can help to see the duration of various events as the updates happen.
