ARIES server crashed a few hours ago and prompted a File System Check (FSCK) upon reboot. The FSCK completed but has cause some problems, namely some corruption of the critical /usr directory that hold many OS files and libraries. We are attempting to restore this partition from a rescue CD. Will update you when we know more.
UPDATE: Most services have been restored and the main two things left are:
1) Email – working to get this back up right now
2) PHP – Some modules need to be compiled in. This will be done after mail is fixed.
[b]UPDATE:[/b] Aries should be 95% back to normal. Websites are up, mail is flowing and Plesk is working. We still have a few things to install (few perl/PHP modules) but these things should affect most people. If you notice something wrong with any sites or email please let us know immediately by emailing firstname.lastname@example.org or submitting a ticket via the online Helpdesk.
Many thanks for your patience!
