One of the interfaces in the load balancer that handles, mail.sonic.net, pop.sonic.net and imap.sonic.net had an interface lock up and stop passing traffic. During the few minutes this was an issue, these services would have been intermittently available. Traffic has been manually rerouted through the standby load balancer. Under nearly every other failure possible the standby load balancer would automatically take over but, unfortunately, its ability to deal with this lockup is not one of them. -Kelsey
