Dear SureMail™ Users,

On October 30th, 2014 we partially lost connectivity to our site 2 datacenter at 3:39 pm EDT. Four minutes later, at 3:43 pm EDT, connectivity was completely lost. Network connectivity went back to normal at 3:52 pm EDT but services took longer to recover.

The network recovered itself after thirteen minutes but our sysadmin team had to bring all the servers and databases back online manually which took longer. By 4:25 pm EDT, 98% of the services were back online and by 5:04 pm EDT, everything was back online.

After an investigation, we found that the loss of network connectivity was due to a crash in both our primary and backup core switches. The crash occurred within a four minute interval and unfortunately, those switches take more than four minutes to complete their boot up sequence. The Exchange servers did an automatic shutdown to prevent any further issues.

Please note that although we strive and hope for 100% uptime, with our current infrastructure we realistically expect, and continue to deliver 99.9+% uptime and this outage continues to support our expected level of service. No mail was lost and users should have experienced at most a short delay in sending or receiving mail.
