Outcome: Successful

Maintenance Summary:

Kynetx will be upgrading the OS versions on all of its servers from Fedora Core 8 to CentOS 5.4_final. In order to perform the upgrade, the host servers will need to be taken offline in turn and upgraded. This maintenance will be one of many over the course of the next ten (10) days.

Impact Statement:

The following sites and services will be unavailable during the maintenance window due to OS upgrade and rebooting activities.

• Corporate website – www.kynetx.com
• Corporate blog – code.kynetx.com
• Corporate news – news.kynetx.com
• Developer website – developer.kynetx.com
• Corporate email – mail.kynetx.com (POP/IMAP/SMTP)
• Appbuilder – appbuilder.kynetx.com
• Accounts – accounts.kynetx.com
• Appdirectory – appdirectory.kynetx.com

Due to load balancing, the impact to the core Kynetx Network Services (init, eval and callback servers) will be minimal.
