As you know we employ a mirror server system for all of our websites; if one goes down, the other starts accepting requests. Previously, it would have taken anywhere from 1 to 5 minutes for our DNS servers to "fail over" from the main site to the backup, but this change should now be nearly instant.
Mail services are still handled differently - if the mail server goes down, incoming mail is queued off-site, and the webmail interface is not accessible. I am looking to add additional redundancy to our mail services in the coming months, but it will always be about saving data (mailboxes) and providing consistant delivery, even if you cannot always access your mailbox.
As always, if you have any questions, respond to this post or e-mail us.
