Due to circumstances beyond our immediate control, we did experience a total server blackout from approximately 10:00am CST till around 7:30pm. Mail services remained online, while the web and ftp/database servers went down for the duration.
All issues seem to be resolved, there was no dataloss and no intrusion or hack of the network (all information was and is still secured).
In a nutshell, an automatic update that was posted in the overnight hours caused a conflict in part of the mail server that took down the web sites. This has all been resolved to the best of our knowledge.
Sorry for the inconvenience.
