[Announce-email] Mail Routing Outage

XMission Internet · Connections // Hosting // Voice <http://www.xmission.com> Mail Routing Outage XMission experienced a major mail routing outage starting at 8:58 A.M. MST which did not fully resolve until approximately 10:50 A.M. Starting at 9:20 A.M. routing was mostly resolved but some mail customers may have had intermittent service with improvements kicking in around 10:00 A.M. All services were restored to standard operational levels by 10:50 A.M. In summary, one of our redundant mail routing servers became unresponsive. Human error resulted in the functioning mail routing server being restarted my mistake, thus halting all mail routing until it could properly re-establish routes. Technical Details For many years XMission's sophisticated email infrastructure has used the resilient and robust LVS (Linux Virtual Server) <http://www.linuxvirtualserver.org/HighAvailability.html> cluster to provide high availability for mail routing. It works incredibly well but when it goes down entirely it can be difficult to get everything nicely re-established under heavy load. ------------------------------------------------------------------------ ★ <http://survey.xmission.com/> Our survey <http://survey.xmission.com/> *t* <https://twitter.com/xmission> Twitter <https://twitter.com/xmission> *f* <https://facebook.com/XMissionInternet> Facebook <https://facebook.com/XMissionInternet> *···* <https://status.xmission.com> Status <https://twitter.com/xmissionstatus> XMission Announcement
