[WN-Ali]

Maintenance ID: 3953
Date: 03/28/2009
Start time (CDT): 03:00:00
End time (CDT): 05:00:00
Services affected: Backend/Private network
Location: Dallas, TX (DAL01)
Duration: 2 hours

==================================================

Description: SoftLayer Engineers will be upgrading the IOS and rebooting the backend/private network routers
across the Dallas network on March 28th 2009 starting at 3:00am CDT.

Customer Impact: Periodically during this maintenance, customers will not have access to backend/private
services (DNS, updates, NAS, iSCSI, etc) as well as server to server communications on the Dallas backend
network. Connectivity from remote cities to Dallas servers and services will also be affected. While the
maintenance window is set for 2 hours, we expect no longer than 15 – 20 minutes of downtime. Customers
are advised to disconnect any NAS and/or iSCSI mounts during this maintenance as a sudden loss
in connectivity could potentially cause file system corruption and/or loss of data.
