We are currently addressing a hardware issue on the Linux hosting cluster, affecting web, ftp and sql services. We will update the ticket when significant progress has been made, at this time we do not have an ETA as the file systems are being checked for errors.
Update: 6 PM EST: At this point over 90% of the service has been restored. We are moving on to more complex, database driven systems at this point.
Update: Saturday 8 PM EST: At this point all sites, even complex SQL driven ones, are online. Service upgraded to new versions of SQL and PHP and a more robust flexible storage array.
